# Smithery documentation

Research date: 2026-08-24

Documentation coverage: not-retrieved.

Reference index, not a mirror of complete vendor documentation. Retrieved pages do not prove the MCP works.

## What it does

A registry and distribution marketplace for MCP servers - "publish once, install anywhere" - that indexes and distributes third-party servers rather than hosting them itself, plus an integrated OAuth/credential layer.

## Access and connection

MCP support: n-a

Access requirements: free to browse; some individual listed servers charge per-call (e.g. one listed server at $0.01-$0.05/call) while others are free/open-source - pricing is per-server, not a single Smithery tier.

Authentication: For the servers listed, auth runs through "agent.pw," described as Smithery's own open-source agent credential vault - Smithery "handles OAuth flows, credential injection, and retries automatically," with connections persisting across chats/harnesses.
