Pull and run the latest multi-arch image (supports both x64 and ARM64):

# Pull the latest image docker pull ghcr.io/vexxvakan/mcp-docsrs:latest # Run the server docker run --rm -i ghcr.io/vexxvakan/mcp-docsrs:latest # Run with custom configuration docker run --rm -i ghcr.io/vexxvakan/mcp-docsrs:latest \ --cache-ttl 7200000 --max-cache-size 200

- latest- Latest stable release (multi-arch)
- v1.0.0- Specific version (multi-arch)

After adding the server, restart the client if it does not discover the tools immediately.

Configure the server using environment variables or command-line arguments:

Retrieves a crate overview with its structure and public API surface from docs.rs.

{ "tool": "crate_lookup", "arguments": { "crateName": "tokio", "version": "1.48.0" } }

Retrieves the crate-level documentation page from docs.rs.

{ "tool": "crate_docs", "arguments": { "crateName": "serde" } }

Searches crates.io for matching crates and returns ranked results using fuzzy and partial name matching.

{ "tool": "crate_find", "arguments": { "query": "rustdoc json", "limit": 5 } }

Retrieves structured symbol metadata for one symbol inside a crate.

{ "tool": "symbol_lookup", "arguments": { "crateName": "tokio", "symbolType": "struct", "symbolname": "runtime::Runtime" } }

Retrieves the full documentation body for one symbol inside a crate.

{ "tool": "symbol_docs", "arguments": { "crateName": "tokio", "symbolType": "struct", "symbolname": "runtime::Runtime" } }
