Sourced.dev

Sourced.dev is an innovative source code search tool designed to enhance how coding agents access and interact with dependency source code from major repositories like PyPI and npm. By using the Model Context Protocol (MCP), this platform enables agents to directly read, search, and navigate source code, eliminating the need for reliance on outdated training data or inefficient web searches. This feature allows for a seamless experience as if the code were available locally.

Key Features

• Extensive Package Tracking: Sourced.dev monitors over 800,000 Python packages and 3,000,000 npm packages, indexing new releases within just 5 minutes of publication.
• Supported Agents: The platform supports a variety of coding agents out of the box, including:
  • Claude Code
  • Claude Desktop (macOS)
  • Cursor
  • VS Code
  • Windsurf
  • Codex
  • Gemini CLI
  • Kiro
  • Zed
  • OpenCode
  • Copilot CLI
  • Antigravity

Advanced Tools for Coding Agents

Sourced.dev provides tools to enhance coding capabilities, including:

Tool	Description
read	Read a file from a package's source code with line numbers.
grep	Search for a regex pattern across a package's source tree.
glob	Find files matching a glob pattern within a package.

All tools allow specifying an ecosystem (e.g., pypi, npm), a package_name, and an optional version, defaulting to the latest.

Ecosystem Support

Sourced.dev currently supports:

• PyPI with over 800,000 packages
• npm with over 3 million packages
• Future plans to include support for Maven/Gradle, RubyGems, and Crates.io (Rust).
