Expose selected GraphQL operations as MCP tools with deliberate transport and authorization boundaries.
Editorial review checked 2026-10-29 against this instruction snapshot. Supporting scripts and runtime behavior remain outside this editorial review.
The guide describes schema sources, operation-backed tools, introspection and transport configuration. It also discusses prompts and request lifecycle hooks. The key architectural decision is which operations an agent may discover and invoke, rather than simply whether the MCP server starts and answers a health check.
Teams connecting an agent to an existing GraphQL API through a controlled MCP tool surface.
Introspection and mutation configuration are not per-invocation human approval. Forwarded credentials, CORS and OAuth settings must match the selected transport. A broad GraphQL operation can expose data or effects beyond what its short tool description suggests.
Works with Claude Code, Claude Desktop, Cursor.

Scores summarize observable discovery signals. Popularity and repository activity apply to the whole repository. Unknown runtime safety earns no certification.
Choose the transport and authentication model, prefer narrowly defined operations and review each tool’s data access and side effects. Configure schema retrieval and credential forwarding explicitly, then connect a development client using the smallest useful permission set.
Test discovery, unauthorized requests, read operations and deliberately denied mutations. Inspect the real operation executed for each tool and verify error handling without disclosing tokens or internal stack details. Record transport and permission assumptions alongside the configuration.
