rustdoc
MCP serverSearchrustdoc gives your AI the ability to search and read Rust documentation, covering the standard library and any crate on crates.io. While helping you write or understand Rust code, it can look up how specific functions, types, or whole crates actually work. The result is answers based on the official docs rather than guesswork.
Use rustdoc in Claude, ChatGPT or Ahel Desktop

Available today. Use it from your connected AI after setup.
No key or account is asked for. Not verified by us yet: Ahel has not run a call through it.
After adding it, ask your AI to look something up in the Rust docs, such as how a standard library function behaves or what a crate you are using provides. It can then search the documentation and read the relevant pages.
What your AI can do with it
- Search Rust documentation by keyword or topic
- Read documentation for the Rust standard library
- Look up docs for any crate on crates.io
- Check how a function or type works before using it in code
- Answer Rust questions using the official documentation
Install rustdoc
The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.
Claude Code
claude mcp add --transport http --scope user rustdoc 'https://ferritin.rs/mcp'Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://ferritin.rs/mcpAdd a custom connector in Settings, paste this address, and approve the sign-in.
Cursor
cursor://anysphere.cursor-deeplink/mcp/install?name=rustdoc&config=eyJ1cmwiOiJodHRwczovL2ZlcnJpdGluLnJzL21jcCJ9Open the link and Cursor adds the server at that address.
ChatGPT
https://ferritin.rs/mcpIn Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.
Codex
codex mcp add rustdoc --url 'https://ferritin.rs/mcp'Run it once, then sign in with codex mcp login rustdoc if the server asks for an account.
From the project's README
As published by jbr/ferritin in README.md. This repository publishes several servers, so only the opening is shown here.
A terminal-based Rust documentation viewer
Ferritin reads rustdoc JSON output to display Rust documentation directly in your terminal. It supports local workspace crates, standard library documentation, and crates from crates.io, with search functionality and modern terminal features including mouse support, syntax highlighting, and clickable links.
