Invoke

Real-world execution for AI agents.

Invoke sits between AI agents and production tools so agent actions do not become wrong CRM updates, duplicate charges, stale approvals, or impossible debugging sessions.

Agents can reason. Production breaks when they execute.

Invoke turns every tool call into a controlled execution:

• validate schema, scope, and policy
• block wrong-entity actions before they touch the tool
• retry safe failures without custom glue
• reconcile unknown outcomes before retrying
• prevent duplicate side effects with idempotency
• freeze risky work for approval, then revalidate before execution
• trace what happened end to end

Quick Start

# 1. Install the CLI
npm install -g @invokehq/cli

# 2. Authenticate to your Invoke runtime
invoke login --base-url https://agentgate-ai.onrender.com --api-key inv_live_...

# 3. Scaffold an execution project
invoke init support-agent --template crm-guardrail
cd support-agent

# 4. Run its local MCP server
invoke dev install

# 5. Register its tools with Invoke
invoke deploy

# 6. Call a tool through the execution layer
invoke call crm_update_customer '{"customer_id":"cust_123","account_status":"review"}'

Then call tools through one execution layer:

import { Invoke } from "./sdk";

const invoke = Invoke.fromEnv();

await invoke.call({
  tool: "linear.create_issue",
  params: {
    team_id: "team_123",
    title: "Investigate webhook drift",
  },
  agentId: "prod-support-agent",
  idempotencyKey: "linear:Investigate webhook drift:team_123",
});

That's it. Your agent still chooses the action. Invoke makes the execution reliable: scoped, checked, retried, reconciled, approved, and traced.

What You Can Build

Invoke ships with wrapper generation for common production tools:

| Command | What it creates | | --- | --- | | invoke wrap github | GitHub MCP wrapper with approval-ready issue creation metadata | | invoke wrap linear | Linear issue workflow wrapper with idempotency hints | | invoke wrap notion | Notion page/document wrapper with Invoke capability metadata | | invoke wrap postgresql --query "SELECT ..." | Scoped PostgreSQL query tool with inferred input schema | | invoke wrap billing-api --openapi openapi.json --base-url https://billing.example.com | OpenAPI-backed wrapper for an internal service |

Or start from an existing MCP server and register its capability card with Invoke:

invoke init billing-agent --template default
cd billing-agent
# run a local MCP endpoint, or edit invoke.json to point at your hosted MCP URL
invoke dev
invoke deploy

See The Aha Moment

Run the local failure demo:

./demo/run_demo.sh

It starts mock tools and shows six production failure modes:

• tool timeout recovered with bounded retry
• payment timeout reconciled before a duplicate charge
• wrong CRM update blocked before the record is touched
• duplicate retry replayed instead of creating a second issue
• stale approval requeued after live state changed
• webhook inconsistency returned as replan_required

The buyer takeaway is simple:

Invoke does not make agents smarter.
It makes their execution bounded when production gets messy.

How It Works

Agents call tools       Invoke controls execution       Production systems
+----------------+      +------------------------+      +------------------+
| SDK / HTTP     |      | Scope + schema check   |      | Linear           |
| MCP clients    |----->| Retry + reconciliation |----->| Slack            |
| workflows      |      | Approval + revalidate  |      | CRM / billing    |
| background jobs|<-----| Trace + outcome        |<-----| Internal APIs    |
+----------------+      +------------------------+      +------------------+

Define - Wrap a service with invoke wrap or register an existing MCP tool with a capability card, schema, risk level, and retry/idempotency hints.

Execute - Agents call /call through the SDK or HTTP. Invoke validates the request, checks scope, classifies the action, and routes it to the right tool.

Control - If the tool times out, partially succeeds, or returns an unknown outcome, Invoke reconciles current state before retrying. If the action is risky, Invoke freezes it for approval and revalidates live state before execution.

Trace - Every call gets a structured execution record your team can inspect, export, and debug.

SDK And API

1. Get an API key

Ask for an Invoke API key, then export it in your shell:

export INVOKE_API_KEY="inv_or_ag_live_..."
export INVOKE_BASE_URL="https://agentgate-ai.onrender.com"

Every API request uses:

X-API-Key: $INVOKE_API_KEY

2. Check available tools

This confirms your key works and shows the tools Invoke can route to.

curl "$INVOKE_BASE_URL/v1/tools" \
  -H "X-API-Key: $INVOKE_API_KEY"

3. Retrieve live context with Exa

This is what we mean by curl /v1/search: your agent asks Invoke for fresh docs or web context before acting. Invoke calls Exa server-side and returns normalized sources plus a trace.

curl -X POST "$INVOKE_BASE_URL/v1/search" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $INVOKE_API_KEY" \
  -d '{
    "query": "latest MCP agent failures",
    "limit": 3
  }'

4. Create a safe execution

This is what we mean by curl /v1/executions: your agent asks Invoke to run a workflow with an idempotency key. If the request is repeated after a timeout, Invoke replays the completed execution instead of creating duplicate side effects.

curl -X POST "$INVOKE_BASE_URL/v1/executions" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $INVOKE_API_KEY" \
  -H "Idempotency-Key: demo-charge-001" \
  -d '{
    "workflow": "safe-tool-execution",
    "agent_id": "revops_agent",
    "input": {
      "params": {
        "customer_id": "cust_acme",
        "amount": 2400,
        "currency": "usd"
      }
    }
  }'

The response includes a durable execution object:

{
  "success": true,
  "execution": {
    "execution_id": "exec_142",
    "workflow_id": "safe-tool-execution",
    "status": "completed",
    "idempotency_key": "demo-charge-001",
    "final_outcome": "completed",
    "trace": [
      {"step": "request_received", "status": "completed"},
      {"step": "unknown_outcome_reconciled", "status": "completed"},
      {"step": "duplicate_retry_blocked", "status": "completed"}
    ]
  }
}

5. Use the SDK

Python:

from sdk import Invoke

invoke = Invoke.from_env()

context = invoke.search("latest MCP agent failures", limit=3)
print(context["results"][0]["url"])

execution = invoke.execute(
    workflow="safe-tool-execution",
    agent_id="revops_agent",
    idempotency_key="demo-charge-001",
    input={
        "params": {
            "customer_id": "cust_acme",
            "amount": 2400,
            "currency": "usd",
        }
    },
)

print(execution["execution"]["execution_id"])
print(execution["execution"]["final_outcome"])

TypeScript:

import { Invoke } from "./sdk";

const invoke = Invoke.fromEnv();

const context = await invoke.search("latest MCP agent failures", { limit: 3 });
console.log(context.results);

const execution = await invoke.execute({
  workflow: "safe-tool-execution",
  agentId: "revops_agent",
  idempotencyKey: "demo-charge-001",
  input: {
    params: {
      customer_id: "cust_acme",
      amount: 2400,
      currency: "usd",
    },
  },
});

console.log(execution.execution);

6. Run packaged workflows

The CLI wraps the same API:

invoke search "latest MCP agent failures"
invoke workflow safe-tool-execution
invoke workflow live-context-retrieval --query "latest OpenAI MCP auth changes before deploying"
invoke workflow failure-trace-visualization

The workflow response includes a buyer-readable visual_flow and a structured trace, for example:

request_received -> context_retrieved -> risk_scanned -> tool_authorized -> execution_completed

7. Call a tool directly

curl -X POST "$INVOKE_BASE_URL/v1/call" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $INVOKE_API_KEY" \
  -d '{
    "tool": "fetch.url",
    "params": {"url": "https://github.com"},
    "agent_id": "research_agent_v1"
  }'

Deploy on Render

This repo is ready to deploy to Render as a Docker web service.

1. Push this repo to GitHub

Render deploys from your Git branch, so make sure the latest backend code is pushed first.

2. Create the service from render.yaml

In Render, create a new Blueprint and point it at this repo. The checked-in render.yaml provisions:

• a Docker web service named invoke-api
• a health check at /health
• env vars for Invoke plus Supabase-backed persistence

3. Fill the required secrets

Render will prompt for:

• INVOKE_API_KEYS: comma-separated API keys allowed to call Invoke
• INVOKE_PUBLIC_URL: your deployed URL, such as https://invoke-api.onrender.com
• INVOKE_ALLOWED_ORIGINS: comma-separated frontend origins allowed to call the API, such as https://invoke.vercel.app
• INVOKE_ALLOWED_ORIGIN_REGEX: optional regex for preview deployments, such as https://.*\\.vercel\\.app
• SUPABASE_URL: your Supabase project URL, for example https://xyzcompany.supabase.co (the backend also tolerates a full /rest/v1 URL if you already copied that)
• SUPABASE_SERVICE_ROLE_KEY: your Supabase service role key
• LINEAR_API_KEY: Linear API key for real issue creation
• LINEAR_TEAM_ID: optional default Linear team UUID for hosted demos
• SLACK_BOT_TOKEN: Slack bot token for real channel listing and message posting
• SLACK_DEFAULT_CHANNEL: optional default Slack channel ID for hosted demos
• EXA_API_KEY: Exa API key for /search and invoke search

4. Create the Supabase tables

Open the Supabase SQL editor and run supabase/schema.sql.

That creates the tables Invoke uses for:

• connected providers
• provider keys
• dynamic tools
• pending approvals
• tool-call traces
• execution records

If Render logs supabase_schema_missing or a PostgREST 404 for invoke_providers, the API is alive but persistence is not installed yet. Run the schema file above in the same Supabase project used by SUPABASE_URL.

5. Verify the deployment

Health check:

curl https://YOUR-SERVICE.onrender.com/health

Tool registry:

curl https://YOUR-SERVICE.onrender.com/tools \
  -H "X-API-Key: YOUR_API_KEY"

Notes

• If SUPABASE_URL and SUPABASE_SERVICE_ROLE_KEY are set, Invoke stores runtime state in Supabase instead of local SQLite files.
• TRACE_DB, TRACE_LOG_FILE, and TRACE_EVENTS_FILE still exist as local fallbacks for development and emergency startup.
• Keep the Supabase service role key server-side only. Do not expose it in browser code or client SDKs.
• If a Vercel frontend calls the Render backend directly from the browser, set TRACE_ALLOWED_ORIGINS and, if you use preview deploys, TRACE_ALLOWED_ORIGIN_REGEX.
• For Slack, the bot token needs chat:write to send messages and channels:read / groups:read if you want the frontend to list channels.

Vercel Frontend -> Render Backend

This repo does not include a Next.js or Vercel frontend yet, but the backend is ready for one.

Frontend env vars:

NEXT_PUBLIC_INVOKE_BASE_URL=https://invoke-ai.onrender.com
NEXT_PUBLIC_INVOKE_API_KEY=YOUR_PUBLIC_DEMO_KEY

Backend env vars on Render:

INVOKE_PUBLIC_URL=https://invoke-ai.onrender.com
INVOKE_ALLOWED_ORIGINS=https://your-frontend.vercel.app
INVOKE_ALLOWED_ORIGIN_REGEX=https://.*\\.vercel\\.app

For server-side calls from a Vercel route handler or server action, use the existing SDK env names instead:

INVOKE_BASE_URL=https://invoke-ai.onrender.com
INVOKE_API_KEY=YOUR_SERVER_SIDE_KEY

Build A Tool Wrapper

Create launch connector wrappers:

invoke wrap github
invoke wrap notion
invoke wrap linear

Wrap a PostgreSQL query:

invoke wrap postgresql \
  --query "SELECT * FROM invoices WHERE id = :invoice_id" \
  --name "invoice lookup"

Wrap an OpenAPI service:

invoke wrap billing-api \
  --openapi openapi.json \
  --base-url https://billing.example.com

This creates a runnable MCP wrapper under wrapped_tools/ with:

• capability metadata
• JSON schema validation
• structured JSON-RPC errors
• idempotency hints
• retry hints
• invoke.register.json for provider onboarding

The npm command is the recommended path. The underlying Python entrypoint remains available for local development:

python agentify.py wrap github

Runtime API

Connect Hosted MCP Gateway

from sdk import invoke

connected = invoke.connect(
    "github",
    owner_email="[email protected]",
    approval_email="[email protected]",
)

print(connected["gateway_url"])
print(connected["tools"][0]["key"])

The gateway returns a hosted endpoint such as https://github.invoke.dev plus an MCP URL and preloaded launch-tool metadata.

TypeScript SDK

import { Invoke } from "./sdk";

const invoke = new Invoke({ apiKey: process.env.INVOKE_API_KEY! });

const result = await invoke.call({
  tool: "fetch.url",
  params: { url: "https://github.com" },
  agentId: "research_agent_v1",
});

const connected = await invoke.connect({
  saas: "linear",
  ownerEmail: "[email protected]",
});

HTTP

All runtime endpoints require X-API-Key.

Create and inspect a v1 execution:

curl -X POST http://localhost:8000/v1/executions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $INVOKE_API_KEY" \
  -H "Idempotency-Key: checkout-retry-001" \
  -d '{"workflow":"safe-tool-execution","input":{"params":{"invoice_id":"inv_123"}}}'

curl http://localhost:8000/v1/executions \
  -H "X-API-Key: $INVOKE_API_KEY"

List registered tools:

curl http://localhost:8000/tools \
  -H "X-API-Key: $INVOKE_API_KEY"

Call a tool:

curl http://localhost:8000/v1/call \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $INVOKE_API_KEY" \
  -d '{
    "tool": "fetch.url",
    "params": {"url": "https://github.com"},
    "agent_id": "research_agent_v1"
  }'

Connect a launch SaaS and get its hosted gateway:

curl -X POST http://localhost:8000/connect/github \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $INVOKE_API_KEY" \
  -d '{"owner_email": "[email protected]"}'

State Revalidation Engine

Agents should act on current truth, not stale assumptions. Use invoke.verify_state(...) before execution when an action depends on critical business state:

from sdk import invoke

state = invoke.verify_state(
    intent="send_invoice_reminder",
    required_fields=["invoice_status", "balance"],
    assumed_state={"invoice_status": "unpaid", "balance": 125},
    state_refetch={
        "tool": "fetch.url",
        "params": {"url": "https://billing.example.com/invoices/inv_123"},
    },
    conditions={
        "invoice_status": "unpaid",
        "balance": "> 0",
    },
)

if state["decision"] != "execute":
    return "Invoice is no longer unpaid. Abort reminder."

Invoke re-fetches current state, compares it with the decision-time assumptions, computes field-level drift, then returns:

• verified / execute: required fields still match and conditions pass.
• blocked / abort: state is missing, changed, or no longer satisfies conditions.
• replan_required / replan: same mismatch path when on_mismatch="replan".

Entity Resolution Tracking

Agents should act on the correct entity, not a guessed ID. Attach entity_resolution to a tool call when the agent resolved a customer, account, invoice, or user before acting:

from sdk import invoke

result = invoke.call(
    tool="billing.send_reminder",
    params={"customer_id": "cust_123", "invoice_id": "inv_456"},
    agent_id="billing_agent",
    entity_resolution={
        "entity_id": "cust_123",
        "source": "crm_lookup",
        "resolved_at": "2026-05-01T12:00:00Z",
    },
)

Invoke logs the resolved entity_id, source, and timestamp into the tool-call trace. Before execution, it compares that entity against IDs in the action params and execution state. If the action points at a different entity, Invoke blocks the call with 409 and never touches the tool.

The same check runs again when a pending approval is approved. If the thawed state now points at a different customer or account, the approval is blocked instead of executing stale work.

Failure Policy Engine

Agents should not guess what to do when tools fail. Add a failure policy to a tool call to make retry, fallback, and escalation behavior explicit and bounded:

{
  "retry": 2,
  "fallback": "secondary_api",
  "on_failure": "escalate"
}

from sdk import invoke

result = invoke.call(
    tool="billing.primary_lookup",
    params={"invoice_id": "inv_123"},
    agent_id="billing_agent",
    failure_policy={
        "retry": 2,
        "fallback": "billing.secondary_lookup",
        "on_failure": "escalate",
    },
)

Invoke enforces a hard retry cap. retry: 2 means one initial attempt plus two bounded retries, never an infinite loop. If the primary tool still fails, Invoke can call the fallback tool once. If everything fails and on_failure is escalate, Invoke creates a pending approval with the failure context for a human to review.

Outcome Reconciliation

Never retry blindly when the outcome is unknown. If a timeout or partial failure happens after a side effect may have occurred, reconcile the action first:

from sdk import invoke

outcome = invoke.reconcile({
    "action": {
        "intent": "charge_customer",
        "params": {"payment_id": "pay_123"},
    },
    "outcome": "UNKNOWN",
    "state_refetch": {
        "tool": "payments.lookup",
        "params": {"payment_id": "pay_123"},
    },
    "conditions": {"charged": True},
})

if outcome["decision"] == "do_not_retry":
    return "Payment already succeeded. Do not charge again."

You can also attach reconciliation to a failure policy:

{
  "retry": 2,
  "on_failure": "escalate",
  "reconcile": {
    "action": "charge_customer",
    "state_refetch": {
      "tool": "payments.lookup",
      "params": {"payment_id": "pay_123"}
    },
    "conditions": {"charged": true}
  }
}

When a failure has an UNKNOWN outcome, Invoke runs reconciliation before retrying. If reconciliation shows the action already succeeded, Invoke returns outcome_reconciled and blocks duplicate retries. If reconciliation shows it did not succeed, bounded retry can continue. If the outcome is still unknown, Invoke escalates or errors according to policy.

Approval Gates

Approval checkpoints carry an execution snapshot: params, variables, tool outputs, action, policy contract, and timestamps. Approval revalidates policy against fresh state before execution and returns executed, cancelled, replan_required, or requeued.

Conditional Approval Contracts

Use a conditional approval contract when an approval is only valid if live business state still matches what the human approved. A contract with intent and conditions creates a pending approval even if the underlying tool is normally low-risk:

{
  "intent": "send_invoice_reminder",
  "conditions": {
    "invoice_status": "overdue",
    "customer_balance": "> 0"
  },
  "threshold": "strict",
  "expires_at": "2026-04-30T15:00:00Z"
}

When approval happens, Invoke fetches or accepts current state, compares it with the frozen approval-time state, and computes drift for each condition key.

• Valid: execute the original action.
• Changed: mark the old approval invalidated and create a fresh pending approval with the live state.
• Expired: cancel before execution.

threshold: "strict" means condition values must still match the approval-time snapshot exactly and the current values must still satisfy every condition. threshold: "conditions" allows value changes as long as the current values still satisfy the conditions.

from sdk import invoke

policy = {
    "rules": [
        {
            "when": "action == git_push and branch == main",
            "effect": "require_approval",
            "intent": "push_to_main",
            "allowed_action": "git_push",
            "reason": "Human approval required for pushes to main",
        }
    ]
}

pending = invoke.call(
    tool="fetch.url",
    params={"url": "https://example.com/repo", "branch": "main"},
    agent_id="dev_agent_v1",
    action="git_push",
    policy=policy,
    execution_state={
        "variables": {"branch": "main"},
        "tool_outputs": {"diff_summary": {"files_changed": 3}},
    },
)

A domain policy can freeze intent-specific work:

{
  "intent": "send_invoice_reminder",
  "condition": "invoice_status == overdue",
  "allowed_action": "send_email",
  "expires_at": "2026-04-30T15:00:00Z"
}

When the human approves, Invoke can accept fresh state from the approver or run a configured state_refetch read tool. It then thaws the checkpoint, validates condition, checks allowed_action and expires_at, and decides whether to execute, cancel, or ask the agent to re-plan.

Open the approval dashboard:

open "http://localhost:8000/dashboard/approvals?api_key=$INVOKE_API_KEY"

For approval notifications, set:

export APPROVAL_SLACK_WEBHOOK_URL="https://hooks.slack.com/services/..."
export APPROVAL_EMAIL_WEBHOOK_URL="https://email-webhook.example/send"

CLI Commands

The CLI gives you the first Invoke project lifecycle:

invoke login --base-url https://agentgate-ai.onrender.com --api-key inv_live_...
invoke init support-agent --template crm-guardrail
invoke dev
invoke deploy
invoke call <tool> '{"json":"params"}'
invoke agents list

Wrapper generation is still available for production tools:

invoke wrap github
invoke wrap notion
invoke wrap linear
invoke wrap postgresql --query "SELECT * FROM users WHERE id = :user_id"
invoke wrap billing-api --openapi openapi.json --base-url http://localhost:8000

Credentials from invoke login are stored in ~/.invoke/credentials.json. invoke dev writes the local MCP URL to .invoke/dev.json, and invoke deploy uses it automatically when invoke.json still has the placeholder MCP URL. Set INVOKE_HOME to override the global credentials location in CI.

Configuration

Local server environment variables:

| Variable | Description | | --- | --- | | INVOKE_API_KEYS | Comma-separated full-access server API keys | | TRACE_API_KEYS | Existing Trace-compatible server API key env var | | INVOKE_API_KEY_SCOPES | JSON scoped-token config for tool allowlists and scopes | | TRACE_API_KEY_SCOPES | Existing Trace-compatible scoped-token env var | | INVOKE_LOG_FILE | Override JSON audit log filename | | TRACE_LOG_FILE | Existing Trace-compatible audit log filename | | INVOKE_ALLOWED_ORIGINS | Comma-separated browser origins allowed by CORS | | TRACE_ALLOWED_ORIGINS | Existing Trace-compatible CORS allowlist env var | | INVOKE_ALLOWED_ORIGIN_REGEX | Optional regex for preview frontend origins such as Vercel previews | | TRACE_ALLOWED_ORIGIN_REGEX | Existing Trace-compatible preview-origin regex env var | | SUPABASE_URL | Optional Supabase project URL for hosted persistence; /rest/v1 suffix is tolerated | | SUPABASE_SERVICE_ROLE_KEY | Optional Supabase service role key for hosted persistence | | SUPABASE_TABLE_PREFIX | Optional Supabase table prefix, default invoke_ | | LINEAR_API_KEY | Optional Linear API key for direct issue creation | | LINEAR_TEAM_ID | Optional default Linear team UUID for hosted demos | | SLACK_BOT_TOKEN | Optional Slack bot token for direct channel listing and posting | | SLACK_DEFAULT_CHANNEL | Optional default Slack channel ID for hosted demos | | FAILURE_POLICY_MAX_RETRIES | Hard cap for per-call failure-policy retries, default 5 | | HOST | Server bind host, default 0.0.0.0 | | PORT | Server bind port, default 8000 |

Client environment variables:

| Variable | Description | | --- | --- | | INVOKE_API_KEY | API key used by the Python and TypeScript SDKs | | TRACE_API_KEY | Existing Trace-compatible client API key env var | | INVOKE_BASE_URL | SDK base URL override | | TRACE_BASE_URL | Existing Trace-compatible SDK base URL override |

Scoped token example:

export INVOKE_API_KEY_SCOPES='{
  "inv_scoped_fetch_read": {
    "scopes": ["tools:read", "tools:call", "traces:read"],
    "allowed_tools": ["fetch.url"],
    "read_only": true,
    "agent_id": "research_agent_v1",
    "envs": ["dev", "prod"],
    "agents": ["research_agent_v1"],
    "workflows": ["market_research"],
    "resources": ["cust_123", "repo:acme/app"]
  }
}'

Supported scopes today: tools:read, tools:call, state:verify, outcomes:reconcile, approvals:read, approvals:write, logs:read, traces:read, and providers:admin.

allowed_tools and read_only gate tool access. envs, agents, workflows, allowed_actions, and resources gate execution context, so a token can mean "this agent may call this tool in prod for this workflow and resource" instead of only re-exposing provider OAuth scopes.

Observability

List recent tool-call traces:

curl http://localhost:8000/traces \
  -H "X-API-Key: $INVOKE_API_KEY"

Export traces:

curl "http://localhost:8000/traces/export?format=langsmith" \
  -H "X-API-Key: $INVOKE_API_KEY"

Local logs:

• JSON audit logs: logs/trace.log
• tool-call traces: logs/tool_calls.jsonl
• trace export formats: JSON, JSONL, LangSmith-shaped, and Helicone-shaped records

When Supabase persistence is enabled, /traces and /traces/export read from Supabase instead of the local JSONL file.

Blast-Radius Demo

There is a demo harness that starts mock tools and runs a production-failure story. It shows how Invoke contains the blast radius when agent execution gets messy:

• tool timeout / transient upstream failure
• partial success with unknown outcome
• wrong CRM update blocked by entity resolution
• duplicated retry
• stale approval
• webhook inconsistency

FLAKY_FAIL_FIRST_N=2 ./demo/run_demo.sh

The demo starts the flaky MCP simulator, a mock tool/CRM MCP server, the Invoke gateway, then runs demo_comparison.py and cleans up processes. The buyer takeaway is simple: Invoke does not make agents smarter; it makes their execution bounded when production gets messy.
