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.
| Tool | What it does |
|---|
get_stock_quote | Current price, day/52-week range, volume — stocks, ETFs, indices |
get_price_history | OHLCV candles plus period return and high/low summary |
search_symbols | Resolve a company name to a ticker |
get_fx_rate | Currency conversion at ECB reference rates |
get_crypto_price | Spot price, 24h change, market cap, volume |
get_crypto_market | Top coins ranked by market cap |
get_sec_filings | Recent EDGAR filings with direct document URLs, filterable by form |
get_sec_financials | As-filed XBRL line items as a time series |
search_sec_filings | Full-text search across every EDGAR filing since 2001 |
get_economic_indicator | World Bank macro series — GDP, inflation, unemployment, debt, trade |
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 Code — no clone needed
claude mcp add finance -e SEC_USER_AGENT="Your Name your@email.com" -- npx -y finance-data-mcp
From source
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"
Claude Desktop
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"].
Any other MCP client
The server speaks MCP over stdio. Run node dist/index.js and point your client at it.

Data sources
Configuration
| Env var | Required | Purpose |
|---|
SEC_USER_AGENT | For SEC tools | EDGAR requires a User-Agent with a real name and email on every request, and returns 403 without one. Format: "Your Name your@email.com". |
IMPORTANT
MCP clients do not pass your shell environment to the server. Set SEC_USER_AGENT in the client config shown above, not in .zshrc.
Development
npm run dev
npm test
npm run smoke
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.
