MCP tools

All tools are read-only and take an optional root (absolute project path).

resolve

List pinned versions and whether their docs are available.

Argument	Type
filter	string	Substring of a package name; also searches transitive dependencies

Each row: ecosystem, name@version, direct or transitive, status (docs ready, version drift, not installed) and the source.

docs

Answer a question from the installed version's docs and API reference.

Argument	Type
query	string, required	Words or identifiers
package	string	zod, npm:zod, pydantic@2.9.2, tokio, github.com/gin-gonic/gin; comma-separate several. Omit to search direct dependencies (a package named in the query is picked automatically)
tokens	integer	Budget, default 1200 (200-20000)

api

Exact signature and doc comment of one symbol.

Argument	Type
symbol	string, required	zod.z.object, z.object, tokio::spawn, axum::Router::route, pydantic.BaseModel.model_dump, gin.Context.JSON
package	string	When the symbol has no package prefix
tokens	integer	Budget, default 1200

Returns the best match (following re-exports), other declarations in the same file (overloads), members for classes, interfaces, structs and traits, and other matches. If no symbol has that name, it falls back to docs.

Add "format": "json" to any call for structured output.
