MISP MCP Server

MISP MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. An MCP server for the open source MISP project.

What you get

A simple Model Context Protocol (MCP) server that exposes MISP (Malware Information Sharing Platform) IOC retrieval functions to MCP-compatible clients like Claude Desktop.

• Get Recent IOCs — Retrieve IOCs added to MISP in the last 24 hours
• IOC Summary — Get statistics and counts by IOC type
• Filter by Type — Get IOCs filtered by specific types (IP, domain, URL, etc.)
• Save to File — Export IOCs to JSON files
• Connection Check — Verify MISP connectivity and configuration

Setting it up

mcp on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Configuration and credentials

You will need 2 environment variables: MISP_URL, MISP_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

• Python 3.8+ - Access to a MISP instance - MISP API key with appropriate permissions

Choosing this one

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by sairambokka; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Before you rely on it

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the misp mcp server does with a few real requests.
