Osim Mcp Server

What is Osim Mcp Server?

Osim Mcp Server is a FastMCP‑based Model Context Protocol (MCP) server that provides query and access capabilities for OSIM (Open Security Information Model) data standard schemas. It is designed for developers and security professionals who need to retrieve schema definitions covering alerts, assets, logs, incidents, and device detections.

How to use Osim Mcp Server?

Run instantly with uvx osim-mcp-server (no installation required) or clone the repository, execute python update_schemas.py to fetch schemas, then run uv sync && uv run python server.py. Configure the server in MCP clients such as Claude Desktop or Cursor by adding the command uvx osim-mcp-server to the client’s MCP settings. The server exposes three tools (list_schema_names, describe_schemas, get_schema) and resource URIs in the format data-standard://{group}/{category}/{title}.
