What it does\nThis MCP server connects your AI coding assistant to the most recent documentation for any specified Rust crate. It prevents the common issue where LLMs suggest outdated APIs or deprecated patterns based on their training data cutoffs by fetching live docs, creating semantic embeddings, and providing accurate context via tool calls.\n\n## Tools\n- `query_rust_docs`: Semantic search for a specific Rust crate's API or usage, returning an LLM-summarized answer based on current documentation.\n\n## Installation\nAdd the following to your `claude_desktop_config.json` (replace `/path/to/` with your actual binary path and set the `OPENAI_API_KEY` environment variable):\n\n`json\n{\n "mcpServers": {\n "rust-docs-serde": {\n "command": "/path/to/rustdocs_mcp_server",\n "args": [\"serde@^1.0\"],\n "env": {\n "OPENAI_API_KEY": "your-key-here"\n }\n }\n }\n}\n`\n\n## Supported hosts\nConfirmed for Claude Desktop and Roo Code (Cursor/Cline).
