@pollinateresearch/mako-mcp

MAKO's paid x402 endpoints (route, pulse, pricing, reputation, verify, markets-aggregate, governance proposal-signal + weekly-brief) wrapped as installable MCP tools. One line of config and any MCP-native agent — Claude Desktop, Hermes Agent, OpenClaw, Cline, Continue.dev — can route through MAKO's trust layer.

What it does

Exposes 8 tools to your agent:

| Tool | Endpoint | Cost (USDC) | Purpose | |---|---|---|---| | mako_route | POST /api/route | $0.05 | Recommend the best x402 service for a task; returns ranked candidates and a signed receipt | | mako_pulse | GET /api/pulse/score | $0.02 | Reliability score for a specific endpoint (status, latency, success rates) | | mako_pricing | GET /api/pricing/index | $0.02 | Live price percentiles for x402 services by category | | mako_reputation | GET /api/reputation/wallet | $0.03 | Operator wallet reputation across MAKO's verification history | | mako_verify | POST /api/agent-commerce/verify | $0.25 | Deep verification of an unfamiliar endpoint (schema, settlement, risk, call plan) | | mako_markets_aggregate | GET /api/markets/aggregate | $0.05 | Top prediction markets across Polymarket + Kalshi + Limitless, normalized and signed. For trading bots, sentiment readers, audit trails. | | mako_governance_proposal_signal | GET /api/governance/proposal-signal | $0.05 | Recent Snapshot proposals for a DAO space — deadlines, choices, scores, urgency. For hourly governance polling. | | mako_governance_weekly_brief | POST /api/governance/weekly-brief | $1.00 | Full source-linked DAO governance weekly brief from Snapshot + Tally, summarized via local Gemma. Markdown + structured metadata. |

Every tool call is paid via x402 from your buyer wallet on Base mainnet. The server transparently handles the 402 → EIP-3009 sign → 200 retry flow. Each response includes a _payment block with the on-chain transaction hash so the agent has proof of payment.

Install

No install needed if you use npx:

npx -y @pollinateresearch/mako-mcp

Or install globally:

npm install -g @pollinateresearch/mako-mcp
mako-mcp

Configure

The server reads configuration from environment variables.

| Variable | Required | Default | Description | |---|---|---|---| | X402_BUYER_PRIVATE_KEY | Yes | — | Hex-encoded private key (0x..., 32 bytes) for the buyer wallet on Base mainnet. Must hold a small USDC balance plus a few cents of ETH for gas. The server refuses to start without this. | | MAKO_BASE_URL | No | https://mako.pollinateresearch.com | Override the MAKO API host. | | MAKO_NETWORK | No | base | x402 network. Accepts viem network names (base, base-sepolia) or x402 chain IDs (eip155:8453). | | MAKO_TIMEOUT_MS | No | 60000 | HTTP timeout per request. | | MAKO_MAX_PAYMENT_USDC | No | 0.50 | Maximum USDC the server will pay for any single tool call. Safety cap. |

Security caveats — read this

The buyer private key controls real money. To minimize blast radius:

• Use a dedicated buyer wallet, not your main wallet. Generate a fresh key for this. Never reuse a wallet that holds significant balances.
• Top up periodically; don't park a large balance. $5–10 of USDC lasts weeks at typical agent volumes (100 route calls = $5).
• The server never logs or transmits the private key. It signs in-process and discards.
• MAKO_MAX_PAYMENT_USDC is a hard ceiling. Even if MAKO returned a malformed 402 asking for $1000, the wrapper refuses anything above your configured max.

Connect to Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "mako": {
      "command": "npx",
      "args": ["-y", "@pollinateresearch/mako-mcp"],
      "env": {
        "X402_BUYER_PRIVATE_KEY": "0xYOUR_BUYER_PRIVATE_KEY_HERE"
      }
    }
  }
}

Restart Claude Desktop. The 8 mako_* tools will appear in the tool picker.

Connect to Hermes Agent

Hermes loads MCP servers via its agent config. See Hermes Agent docs for the latest schema. Example:

mcp_servers:
  - name: mako
    command: npx
    args: ["-y", "@pollinateresearch/mako-mcp"]
    env:
      X402_BUYER_PRIVATE_KEY: ${X402_BUYER_PRIVATE_KEY}

See examples/hermes-agent-config.md for the full integration walkthrough.

Connect to OpenClaw

OpenClaw's MCP loader: drop the same npx command into its mcp_servers block. Pairs naturally with openclaw-x402 — mako-mcp adds the routing layer above the payment layer. See examples/openclaw-config.md.

Connect to Cline / Continue.dev / Zed / others

Any MCP-native client that accepts a command + env config works. The pattern is always the same:

"command": "npx",
"args": ["-y", "@pollinateresearch/mako-mcp"],
"env": { "X402_BUYER_PRIVATE_KEY": "0x..." }

}

mako_markets_aggregate

Top prediction markets across Polymarket, Kalshi, and Limitless, normalized into one signed response.

{
  "query": "bitcoin",                          // optional substring filter on market title
  "category": "crypto",                        // optional: "crypto" | "sports" | "politics" | "world" | "culture" | "economics" | "entertainment"
  "sources": "polymarket,kalshi,limitless",    // optional comma-separated source list

  "min_liquidity_usd": 0,                      // optional liquidity floor — Limitless doesn't report liquidity, so any min > 0 will skip Limitless markets
  "include_resolved": false                    // optional; include recently-resolved markets
}

Returns ranked markets with normalized fields (title, outcomes, prices, 24h volume, liquidity, expiration, source URL), per-platform editorial reliability scores flagged score_source: static_v1 (live pulse-ledger probes coming in v0.3), and an EIP-191 signed receipt over RFC 8785 canonical JSON.

Use cases: trading bots that need one-call multi-source market data, AI agents reading market sentiment as a forward-looking signal, compliance-conscious traders who want signed attestations of point-in-time market state.

mako_governance_proposal_signal

Recent Snapshot proposals for a DAO space. Lightweight ($0.05) polling tool — agents call this hourly and only escalate to the full weekly brief when something interesting hits.

{
  "snapshot_space": "arbitrumfoundation.eth",     // default 'arbitrumfoundation.eth'
  "snapshot_state": ["active", "pending"],        // subset of ["active","pending","closed"]
  "snapshot_order_direction": "asc",              // "asc" | "desc"
  "limit": 5                                      // 1-25, default 5
}

Returns proposal metadata (title, body excerpt, choices, scores, state, end timestamp, urgency flags) with a signed receipt. No model summarization — pure source-linked passthrough.

mako_governance_weekly_brief

Premium tier ($1.00) — the canonical "one-call DAO weekly digest" product. Pulls from Snapshot + Tally, summarizes via local Gemma model, returns Markdown + structured proposal metadata.

{
  "client_name": "Agentic Market Buyer",          // optional, default "Agentic Market Buyer"
  "snapshot_spaces": ["arbitrumfoundation.eth"],  // up to 10 spaces
  "snapshot_states": ["active", "pending"],       // subset of ["active","pending","closed"]
  "snapshot_order_direction": "asc",
  "tally_governor_ids": [],                       // optional Tally governor IDs
  "tally_organization_ids": [],                   // optional Tally org IDs
  "limit": 5,                                     // proposals per source, max 25
  "max_summaries": 10,                            // optional cap on model summaries
  "max_body_chars": 4000,                         // optional body truncation
  "num_predict": 256,                             // optional model token budget
  "timeout": 30,                                  // optional per-summary timeout seconds
  "skip_model": false,                            // true → deterministic excerpts only
  "write_artifacts": false                        // true → server persists brief artifacts
}

Returns { markdown, proposals[], request_id, receipt, _payment }. Use skip_model: true for fully deterministic output (no LLM, faster, lower-variance) when downstream consumers need byte-stable input.

Manual smoke test
