truesource-mcp

First-hand market signals your AI agent can actually cite.

An MCP server wrapping TrueSource — a crawler and AI-retrieval stack that watches things which have already happened and carry a verifiable source: exchange filings, government procurement awards, R&D expansion moves, northbound holdings, and official macro releases.

It does not summarise analyst reports and it does not emit buy/sell calls. Every signal comes with a date and where it came from.

Tools

Procurement is the most distinctive one: a contract award is a fact that has already occurred, which is a harder input than a forecast.

Quick start

You need an API key first — see below.

Claude Desktop / Cursor

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "truesource": {
      "command": "uvx",
      "args": ["truesource-mcp"],
      "env": { "HUNTER_API_KEY": "hunt_tools_xxx" }
    }
  }
}

Command line

# no install needed
HUNTER_API_KEY=hunt_tools_xxx uvx truesource-mcp

# or install it
pip install truesource-mcp
HUNTER_API_KEY=hunt_tools_xxx truesource-mcp

API key

This server has no keyless mode, and cannot have one — the upstream gateway returns 403 without a key.

The reason is cost: truesource_scout runs real crawlers plus a Gemini search on every call, so each invocation spends money on third-party APIs. Anonymous access would be trivially expensive to abuse and impossible to attribute.

Get one at https://hunter.agentpit.io/dev/api-keys — sign in, click 申请 API Key, copy the hunt_tools_… key (shown once), set it as HUNTER_API_KEY.

If the key is missing, this server does not return sample data or a fake success. It returns an error that tells you exactly where to get a key.

Environment variables

stdio is what Claude Desktop, Cursor and uvx use. Run a remote transport only if one long-running server should serve several clients — and prefer streamable-http, since the MCP spec marks SSE as deprecated.

Three things that will bite you otherwise

grey is not green. In daily_brief, an alert level of grey means no signal was collected for this ticker in the last 3 days. That may mean the stock was quiet, or it may mean coverage missed it. It does not mean "safe".

An empty result is a conclusion, not a failure. alert_signals returning nothing means these tickers crossed no threshold in the last 26 hours. That is information. This server never dresses an empty result up as an error, and never fills it with placeholder rows.

Truncation is always disclosed. Responses are capped at TRUESOURCE_MAX_ITEMS (40 by default). When that bites, the payload carries truncated: true, the real total, and a note not to draw conclusions from the visible slice. Raise the cap or narrow the date range instead.

truesource_report also will not silently fall back to scout when a ticker isn't one of the 35 pre-built names. Scout costs 30–60 seconds and real money — that choice should be made deliberately, not happen behind your back.
