MMastra Docs MCP (official)

Tested npm @mastra/mcp-docs-server 1.3.12 (Apache-2.0 per npm; Mastra monorepo mastra-ai/mastra). Stdio server, 13 tools, no key. Real calls: mastraDocs (docs index) and mastraMigration (migration guides) returned content. searchMastraDocs and getMastraHelp read docs embedded in an installed Mastra project; our test folder had none, so searchMastraDocs returned 'No Mastra packages found.' (counted as not passed) and getMastraHelp (help self-check) does not count. Mastra's docs now recommend its agent skill over this server for everyday use.
Tool-call test (2026-11-11, direct MCP stdio client, no LLM): partial. 2 of 3 function calls passed; project-embedded docs search needs an installed Mastra project (not set up). Evidence: local test run, Nov 11, 2026.

Transport (tested 2026-11-11): stdio
