FixGraph MCP Server is the MCP (Model Context Protocol) server implementation for FixGraph, enabling users to directly search and contribute to the FixGraph knowledge base from any MCP-compatible AI assistant. FixGraph is a community-verified knowledge base of technical error fixes, with over 25,000 real-world technical error fixes spanning multiple domains such as software, vehicles, home systems, and appliances.
Main capabilities:
- Search: Free, no API key required. Users can have an AI assistant search for fixes for a specific error or problem, such as searching for the issue where a Docker container exits immediately, npm ERESOLVE dependency conflicts, ERR_OSSL_EVP_UNSUPPORTED, etc.
- Contribute: Submitting a fix or issue requires an API key. Users can register to obtain a key; registration is instant, with no OAuth authentication and no waiting.
- Community verification: The fixes in the knowledge base are community-verified and come with trust scores and a fix verification mechanism (inferred from the description, but the original materials do not explicitly mention trust scores and verification details; this is based only on the "community-verified" wording in the description).
How to use:
- Add the FixGraph MCP server to the MCP configuration. It supports MCP-compatible AI assistants such as Claude Desktop, Cursor, and Windsurf.
- Configuration example (from official materials):
- Search requires no API key and can be used directly.
- To submit a fix or issue, an API key must be added.
- Register an API key: You can visit fixgraph.netlify.app/developers to register; registration is instant and requires no OAuth.
- After installation, you can ask queries to the AI assistant, such as:
- "Search FixGraph for Docker container exits immediately"
- "Find fixes for npm ERESOLVE dependency conflict"
- "Check if there is a verified fix for ERR_OSSL_EVP_UNSUPPORTED"
Applicable scenarios:
- When developers encounter software errors, quickly find community-verified fixes.
- When needing to resolve vehicle, home system, or appliance failures, find related fix knowledge.
- Integrate directly into an AI assistant without switching applications.
Limitations:
- Search is free and requires no API key, but submitting a fix or issue requires an API key.
- Currently, only MCP-compatible AI assistants are supported.
- Other limitations (such as request rate limits, data formats, etc.) are not yet provided.
