Overview

What is MISP MCP Server?

MISP MCP Server is a Model Context Protocol (MCP) server that exposes MISP (Malware Information Sharing Platform) IOC retrieval functions to MCP-compatible clients like Claude Desktop. It allows users to fetch recent indicators of compromise, get summary statistics, filter by type, export to JSON, and verify MISP connectivity.

How to use MISP MCP Server?

Install Python dependencies, set the MISP_URL and MISP_API_KEY environment variables, and run python misp_mcp_server.py. Then configure an MCP client (e.g., Claude Desktop) with the command python and the absolute path to the script, along with the environment variables. The server listens via STDIO and exposes five tools and one resource.
