What is the Couchbase (Vector & NoSQL) MCP Server?
Connect your Couchbase (Capella or self-hosted) cluster to any AI agent and take full control of your NoSQL and vector data through natural conversation.
What you can do
- Vector Search (KNN) — Execute direct searches mapping AI embeddings to locate textual similarities using native vector indices
- N1QL SQL-for-JSON — Push absolute explicit querying using N1QL (SQL for Couchbase) to retrieve complex JSON structures across your buckets
- Document CRUD — Fetch elaborate internal properties and retrieve exact Data maps from specific collections using unique document keys
- Full-Text Search (FTS) — Perform structural text-based extraction matching query strings across advanced FTS search indexes
- Schema Navigation — Identify bounded routing spaces including Buckets, Scopes, and Collections to understand your data organization
- Index Auditing — Enumerate explicitly registered Search Indexes and verify vector definitions and cluster configurations
How it works
- Subscribe to this server
- Enter your Couchbase URL, Database Username, and Database Password
- Start querying your NoSQL and vector data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- AI Developers — test and debug vector similarity searches and semantic matching for RAG applications
- Data Architects — audit NoSQL data structures and verify collection organization across environments
- Database Administrators — monitor search indexes and execute N1QL queries to verify data consistency
- Product Teams — quickly prototype search features and audit JSON document schemas through natural language
Built-in capabilities (7)

Frequently asked questions
Can my agent perform K-Nearest Neighbor (KNN) vector searches in Couchbase?
Yes. Provide the search index name, the vector embedding array, and the number of results (k). The agent uses Couchbase's native vector capabilities to locate the most semantically similar documents in your cluster.
How do I execute a N1QL query through the agent?
Use the 'execute_n1ql_query' tool and provide your SQL-like statement. The agent will fetch the structural JSON blocks directly from Couchbase, allowing you to perform complex data retrieval using familiar SQL syntax.
Can I search documents using full-text query logic?
Absolutely. The 'fts_search' tool leverages Couchbase's Full-Text Search (FTS) engine. Provide an index name and a boolean query string to perform structural text-based extraction across your document trees.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Couchbase (Vector & NoSQL) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
