Quickbase MCP Server

# Relationship Tools ## Critical: API Endpoint Pluralization Read uses **plural**, writes use **singular**: | Operation | Method | Path | |-----------|--------|------| | Get | GET | `/tables/{tableId}/relationships` | | Create | POST | `/tables/{tableId}/relationship` | | Update | POST | `/tables/{tableId}/relationship/{id}` | | Delete | DELETE | `/tables/{tableId}/relationship/{id}` | Using the wrong form returns HTTP 404. See [.claude/docs/quickbase-api-pitfalls.md](../../../.claude/docs/quickbase-api-pitfalls.md) for full context. ## Update Uses POST, Not PUT The update endpoint uses `POST`, not `PUT` or `PATCH`. This is a Quickbase API convention for relationship mutations.
