opensrc

name	opensrc
description	Fetch dependency source code to give AI agents deeper implementation context. Use when the agent needs to understand how a library works internally, read source code for a package, fetch implementation details for a dependency, or explore how an npm/PyPI/crates.io package is built.
allowed-tools	Bash(vp exec opensrc:*)

Source Code Fetching with opensrc

Use the repo-local opensrc dev dependency through Vite+:

vp exec opensrc fetch <package-or-repo>
vp exec opensrc path <package-or-repo>
rg "pattern" "$(vp exec opensrc path <package-or-repo>)"

Prefer fetch when setting up context and path when reading or searching source.

Examples:

vp exec opensrc fetch @modelcontextprotocol/sdk @ai-sdk/mcp
vp exec opensrc fetch github:modelcontextprotocol/use-mcp github:modelcontextprotocol/inspector
rg "client_id_metadata_document_supported" "$(vp exec opensrc path @modelcontextprotocol/sdk)"

Cached source lives under ~/.opensrc/. Do not vendor whole upstream repos into this project. If a file is copied into docs/reference/prior-art/, treat it as a curated snapshot and record the authoritative opensrc source path in docs/reference/opensrc-sources.md.
