SpandrelMCP reference implementation

Spandrel MCP

A hosted Model Context Protocol server for the Spandrel knowledge graph — read-only, public, no auth.

Endpoint POST

https://mcp.spandrel.org/mcp

Streamable HTTP transport. Reads the published bundle at https://spandrel.org via RemoteGraphStore; no local data.

Tools

Nine read-only tools map one-to-one to Spandrel's GraphQL read surface: context, search, navigate, get_node, get_references, get_content, get_graph, validate, get_history.

Wire it up

claude mcp add spandrel https://mcp.spandrel.org/mcp \
  --transport http --scope user

Fork for your own graph

This is a reference implementation. Clone trevorfox/spandrel-mcp, set SPANDREL_BUNDLE_URL to the root of your published bundle, and deploy to Vercel. Point a subdomain at it. That's the whole change.
