finance-mcp

Live financial data for any LLM agent. Stock quotes · crypto · SEC filings · XBRL financials · FX · macro indicators

Why

Most finance APIs want a signup, a key, and a credit card before your agent can answer "what's Apple trading at?"

finance-mcp wraps five genuinely free public sources behind ten MCP tools. Clone, build, point Claude at it — done. The only configuration is an email address, and only because the SEC insists on one.

How it fits together

The shared HTTP layer paces requests per host, retries 429/403/5xx with exponential backoff, honours Retry-After, and caches responses in memory — 30s for quotes, hours for filings and macro series.

Quickstart

claude mcp add finance -e SEC_USER_AGENT="Your Name your@email.com" -- npx -y finance-data-mcp

git clone https://github.com/AdityaSBisht/finance-mcp.git
cd finance-mcp
npm install
npm run build
claude mcp add finance -e SEC_USER_AGENT="Your Name your@email.com" -- node "$(pwd)/dist/index.js"

Add to claude_desktop_config.json — on macOS, ~/Library/Application Support/Claude/claude_desktop_config.json — then restart the app:

{
  "mcpServers": {
    "finance": {
      "command": "npx",
      "args": ["-y", "finance-data-mcp"],
      "env": {
        "SEC_USER_AGENT": "Your Name your@email.com"
      }
    }
  }
}

To run from a local clone instead, use "command": "node" with "args": ["/absolute/path/to/finance-mcp/dist/index.js"].

The server speaks MCP over stdio. Run node dist/index.js and point your client at it.

Notes and limitations

• Yahoo rate-limits by IP, and it cares what you claim to be. Sending a spoofed desktop-browser User-Agent gets you throttled hard — measured 0/8 successful requests with a Chrome UA versus 8/8 with an honest finance-mcp/0.1 one, alternating back to back. This server identifies itself honestly for that reason; don't "fix" it by pretending to be a browser. FX is served from the ECB instead, which has no rate limit.

• Quotes may be delayed up to ~15 minutes and are not exchange-official.

• SEC XBRL figures are as-filed. get_sec_financials labels each row by the period it covers, not the fiscal year of the filing it came from — EDGAR's own fy field describes the filing, so a 10-K restating a prior year would otherwise mislabel it.

• search_sec_filings ranks by EDGAR's relevance, which favours companies with your query in their name.

• World Bank data is annual and typically lags one to two years.
