Sourced
Search real PyPI and npm package source from your agent when choosing libraries or debugging unfamiliar APIs.
Overview
Sourced is an MCP server for the Build phase that searches published PyPI and npm package source code for coding agents.
What is this MCP server?
- Search source across PyPI and npm registries
- Remote streamable-http MCP at mcp.sourced.dev
- No local clone required to peek at package implementations
- Version 1.0.1 with website sourced.dev
- GitHub repository RyanCodrai/sourced
- Covers PyPI and npm package source search
- Remote endpoint https://mcp.sourced.dev/mcp
- Server version 1.0.1

What problem does it solve?
Agents hallucinate package APIs because they only see docs summaries, not the actual module source on the registry.
Who is it for?
Indie developers who pick npm/pip packages weekly and want the agent to read upstream code before wiring integrations.
Skip if: Private registries, monorepo-only code with no PyPI/npm publication, or offline-only workflows without HTTP MCP access.
What do I get? / Deliverables
After adding the Sourced remote MCP, your agent can query real PyPI and npm source to ground integration and dependency decisions.
- Agent-grounded answers from real published package source
- Faster integration decisions without manual tarball or repo cloning
- Reduced API hallucination when wiring third-party libraries
Recommended MCP Servers
Journey fit
Dependency and integration choices happen while you build; reading upstream source beats guessing from README snippets alone. Integrations is the shelf for tooling that inspects third-party packages you might wire into your app.
How it compares
Registry-wide source search MCP, not a single-repo code search skill or package installer.
Common Questions / FAQ
Who is Sourced for?
Solo builders and small teams using MCP-enabled agents who depend on public PyPI and npm packages and need trustworthy source lookup.
When should I use Sourced?
Use Sourced while scoping integrations or implementing features that depend on third-party libraries you have not read end-to-end.
How do I add Sourced to my agent?
Add the remote MCP URL https://mcp.sourced.dev/mcp (streamable-http) in your client MCP settings and enable the Sourced tools for your session.
