finance-mcp
Live financial data for any LLM agent. Stock quotes · crypto · SEC filings · insider trades · XBRL financials · FX · macro
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 eleven MCP tools. No key for any of them. The only configuration is an email address, and only because the SEC insists on one.
The one you can't get anywhere else
Company insiders — officers, directors, 10% owners — must report every trade in their own stock to the SEC within two business days. It's public, it's structured, and essentially nobody reads it.
The catch is that most of it means nothing. Options vest. Shares get withheld to pay the tax on that vesting. None of it is a decision, and all of it gets reported as "insider selling."
get_insider_activity separates the two. Real output, Apple, one week in June:
OPEN-MARKET (a deliberate decision to trade)
Sold: 5 filing(s) 302.92K shares ≈ $87,566,268.55
MECHANICAL (vesting, option exercises, tax withholding — no decision): 1 filing(s)
Newstead Jennifer — SVP, GC and Secretary
2026-06-15 +30.10K @ — Option exercise / conversion
2026-06-15 −16.24K @ $296.42 Shares withheld for taxes ← not a trade
LEVINSON ARTHUR D — Director
★ 2026-05-06 −149.53K @ $284.57 Open-market sale ← a real decision
★ 2026-05-06 −100.47K @ $285.04 Open-market sale
2026-05-06 −5.00K @ — Gift
Same company, same month. One of those is a signal; the other is payroll. Every row links to the filing it came from.
It reports what was disclosed and does not interpret it. Insider buying and selling both have innocent explanations, and neither predicts the share price.

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/adididitagain/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.

Notes and limitations
- Yahoo rate-limits by IP, and it cares what you claim to be. Sending a spoofed desktop-browser
User-Agentgets you throttled hard — measured 0/8 successful requests with a Chrome UA versus 8/8 with an honestfinance-mcp/0.1one, 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_financialslabels each row by the period it covers, not the fiscal year of the filing it came from — EDGAR's ownfyfield describes the filing, so a 10-K restating a prior year would otherwise mislabel it. search_sec_filingsranks 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.
- Insider data is only as complete as the window you read.
get_insider_activityreads the most recentlimitForm 4s and reports how many it skipped — a large company files hundreds a year, so a small limit shows a recent slice, not a full picture. Form 4s are due within two business days of the trade, so there is a short reporting lag.
