EdgeDepth Research MCP Server

@edgedepth/research-mcp is the official, read-only Model Context Protocol server for EdgeDepth, a market microstructure search engine over recorded Binance USDT-M crypto and TradFi perpetuals. Use it from Claude, Cursor, Codex, or any MCP client to find every verified occurrence of a market condition, inspect forward outcomes across the complete matched set, compare against an eligible baseline, and open replay-linked evidence.

Every result includes counts with denominators and a reproducibility key. Same key, same bytes.

Why use EdgeDepth Research?

• Search recorded market microstructure: query a closed, versioned feature registry covering order flow, price action, volatility, funding, open interest, positioning, candle formations, and liquidations.
• Keep the denominator: every count reports the eligible population and exclusions behind it. Missing data is absent, never silently changed to zero.
• Measure outcomes without lookahead selection: forward returns, MFE, and MAE are computed over all occurrences. Outcome fields cannot be used as filters.
• Compare matched and baseline populations: deterministic cohort results put the matched distribution beside every other eligible predicate-false bucket.
• Audit and replay the evidence: results carry a reproducibility key, and representative occurrences include authenticated web handoffs to the exact recorded market moment.
• Stay read-only: the MCP tools search and retrieve research. They do not trade, modify alerts, publish reports, or write account data.

Choose a connection

The package exposes one tool core through two transports:

• Hosted MCP (recommended): connect to https://mcp.edgedepth.com/mcp over Streamable HTTP and authorize once in your browser. No API key to copy.
• Local stdio: run npx -y @edgedepth/research-mcp with an EdgeDepth API key.

Connect

Claude Desktop

In Settings > Connectors > Add custom connector, enter:

https://mcp.edgedepth.com/mcp

Complete the EdgeDepth browser authorization prompt.

Cursor (~/.cursor/mcp.json)

{
  "mcpServers": {
    "edgedepth-research": {
      "url": "https://mcp.edgedepth.com/mcp"
    }
  }
}

Codex (~/.codex/config.toml)

[mcp_servers.edgedepth]
url = "https://mcp.edgedepth.com/mcp"

Then run:

codex mcp login edgedepth

Remove any old bearer_token_env_var line before using browser OAuth.

Local stdio with npx

Create a key on the EdgeDepth Developer page, then add:

{
  "mcpServers": {
    "edgedepth-research": {
      "command": "npx",
      "args": ["-y", "@edgedepth/research-mcp"],
      "env": {
        "EDGEDEPTH_API_KEY": "edk_live_YOUR_KEY"
      }
    }
  }
}

Local stdio requires Node.js 20 or newer. Use the research:read key scope for the read-only tools and add research:interpret only when you need interpret_prose.

Recommended agent workflow

1. Call list_features first. It is the live, closed grammar and prevents invented fields.
2. Call list_instruments to check the manifest-derived universe, coverage, and provenance.
3. If starting from natural language, call interpret_prose. It returns a proposed document and never executes it.
4. Inspect or show that proposal, then pass the exact document to run_scan.
5. Read rates from outcomes_summary, which covers all occurrences. Page rows are examples, never the denominator.
6. Return the full reproducibility key with the answer. Use next_page only with a cursor returned by the API.

Example instruction for an MCP client:

Call list_features first, then list_instruments for btcusdt and ethusdt.
Propose an exact query for elevated VPIN and one-sided taker flow over the last
seven complete UTC days. Show me the proposed document before running it.
Report counts with denominators, summarize outcomes over all occurrences, and
include the full reproducibility key.

Tools

| Tool | What it does | | --- | --- | | list_features | Returns the closed grammar registry: feature ids, types, ranges, operators, windows, sequence rules, limits, and error codes. | | list_instruments | Returns the research universe and coverage. The default is a compact summary; use symbols: [...] for selected full records or full: true for the verbatim canonical universe. | | interpret_prose | Turns prose into a proposed query document. It does not execute the query. Optional time_zone accepts an IANA time zone for calendar planning. | | run_scan | Executes a research_query.v2 document and returns canonical result bytes with counts, denominators, outcomes, and the reproducibility key. | | next_page | Continues a prior scan with its opaque cursor. Never construct cursors manually. | | snapshot_at | Reads registry feature values, window aggregates, and fired rules as of a recorded moment. | | base_rate | Counts matches and eligible buckets for one clause over a window. | | commonality | Finds the deterministic intersection across multiple moments with selection-bias caveats included. | | get_report | Retrieves a published report by its 8-character canonical hash. | | run_cohort | Compares what followed every match with what followed every other eligible predicate-false bucket. |

All tools are read-only.

Research contract

• Validation failures pass through as 422 {"errors":[{"code":"...","message":"..."}]}.
• Transport failures use the {"error","code"} envelope.
• Contract codes are machine-actionable. For errors such as UNSUPPORTED_FEATURE or OUTCOME_IN_PREDICATE, call list_features, repair the document, and retry.
• Deterministic tools are exact-document, UTC-only tools. interpret_prose may use a time zone to plan dates, but run_scan, run_cohort, and base_rate never reinterpret calendar language.
• Reruns and ETag 304 Not Modified revalidations are free. list_instruments ETags are scoped to the requested summary, symbol projection, or full representation.

REST API and documentation

The MCP server is a thin, deterministic interface to the public EdgeDepth Research API:

• REST API quickstart
• Authentication and API keys
• Credits, caching, and limits
• Versioned query grammar
• Reproducibility contract
• Worked API examples
• MCP connection guide
• How EdgeDepth Research works
• What you can ask

The default REST base used by the stdio package is https://app.edgedepth.com/api/v1/research.

Environment

Local stdio

| Variable | Default | Purpose | | --- | --- | --- | | EDGEDEPTH_API_KEY | None | Required for stdio tool calls. | | EDGEDEPTH_API_BASE | https://app.edgedepth.com/api/v1/research | Optional REST API base override. |

Hosted server operators

| Variable | Default | Purpose | | --- | --- | --- | | EDGEDEPTH_OAUTH_EXCHANGE_URL | http://127.0.0.1:3002/api/mcp/oauth/exchange | OAuth access-token exchange endpoint. | | MCP_INTERNAL_SECRET | None | Required internal assertion secret; must match the web app. | | PORT | 3003 | HTTP listen port. | | HOST | 127.0.0.1 | HTTP listen host. |

Authentication and security

The hosted server uses browser OAuth. It validates opaque access tokens, exchanges them for separate short-lived internal assertions, and never passes the OAuth access token to the REST API. The MCP server is stateless and stores no user credentials.

Compatible clients rotate refresh tokens silently while the connection remains active. Review or revoke access at EdgeDepth Connected Apps.

API keys remain available for scripts, local stdio, and MCP clients without browser OAuth. Treat an edk_live_... key as a secret and never commit it to source control.

npm install

npm run typecheck

TypeScript builds to dist/. Example nginx locations, systemd hardening, and operator environment values live under deploy/. Production deployment and npm publishing remain operator actions.
