# Model Context Protocol - official servers repo documentation

Research date: 2026-08-24

Documentation coverage: partial.

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

## What it does

The official reference-implementation repository for MCP, "managed by Anthropic, but built together with the community" - ships a small set of maintained example servers (Everything, Fetch, Filesystem, Git, Memory, Sequential Thinking, Time) intended as educational references, not production integrations.

## Access and connection

MCP support: official

Access requirements: free (open source; dual-licensed Apache 2.0 for new contributions, MIT for existing code)

Authentication: Per-server - individual servers take credentials (e.g. API tokens) via environment variables or CLI args where needed; the repo itself has no central auth layer.

Research checked: 2026-08-24

These details come from catalog research. Check vendor sources for current setup instructions; this is not proof of a tested connection.
