Mcp Factcheck

Overview

Mcp Factcheck is an MCP server that validates content against the MCP specification using semantic search and AI. It enables Claude, Cursor, VS Code, and other MCP clients to fact-check information automatically by integrating validation capabilities directly into your workflow.

The server runs locally via Docker using the image ghcr.io/carlisia/mcp-factcheck:v1.0.0 and communicates over stdio. You'll need to provide your OPENAI_API_KEY as an environment variable to authenticate with the service. The v1.0.0 release is published under the MIT license with source code available at carlisia/mcp-factcheck on GitHub.

Mcp Factcheck appears in the Search category on mcp.site and works with all MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim the listing to verify ownership and keep information up to date.
