Couchbase MCP

Couchbase is a distributed NoSQL database with a JSON document model and a SQL dialect called SQL++, previously known as N1QL. The official MCP server connects an AI client to a Capella cloud cluster or a self managed deployment and turns the database into a set of callable tools, so an agent can explore data and answer questions about it instead of relying on a schema someone pasted into the prompt. The server lets an agent enumerate buckets, scopes, and collections, inspect the inferred structure of a collection so it knows which fields actually exist before writing a query, fetch a document by key, and run SQL++ statements with results returned as structured data. Document upsert and delete tools are available for write workflows. Because the target is often a live cluster, the server ships a read only mode and explicit flags that gate any mutating call, which lets a team hand an assistant real production access without handing it the ability to change records. Authentication uses standard cluster credentials or a Capella API key, so an agent inherits the same role based access control as a human user. It suits developers exploring an unfamiliar dataset, support engineers answering data questions in plain language, and teams that want an assistant to draft and validate SQL++ against a real schema rather than guess at field names.
