What a financial MCP server does
An MCP server exposes tools that an AI client can call through the Model Context Protocol. A financial MCP server's tools fetch market data, company financials, filings or news, so the model answers from data and not from memory.
This page covers servers for developers and AI agents. Servers that connect your own bank or brokerage accounts are a different category and are not listed.
How to choose a financial MCP server
Three questions decide it.
- 01
What does your agent need back?
Prices, fundamentals and statements, or text: passages that answer a question, with a source.
- 02
Hosted or local?
A hosted server is a URL you add to your client. A local server runs on your machine with Python or Docker.
- 03
How do you get access?
Some servers need no key, some need a free key, and some need a paid plan.
The servers
Finks
Best for: Agents that search in plain English and need the passage that answers, with its source.
Most financial MCP servers map one tool to one data endpoint, and your agent picks the endpoint. Finks takes a plain-English query and returns the passages that answer it, from news, SEC filings and earnings call transcripts. A source is attached to every result, so your agent can check its work.
- Maker
- Finks
- Hosting
- Hosted, streamable HTTP, Bearer key on every request; the server holds no key. Copy the server URL from the Finks API console.
- Access
- Get set up in minutes. Free tier, no card required.
- Coverage
- News, SEC filings and earnings call transcripts. Filings: reportable events in 8-K filings, plus 10-K and 10-Q reports, each linked to the filing on sec.gov. How far back you can search depends on your plan.
- Tools
