What is the Neon (Serverless PostgreSQL) MCP Server?
Connect your Neon account to any AI agent and take full control of your serverless PostgreSQL infrastructure, database branching, and project orchestration through natural conversation.
What you can do
- Project Orchestration — List all managed serverless workspaces and retrieve detailed regional deployment metrics and regional Caps directly from your agent
- Zero-Copy Branching — Instantly spawn brand new database branches (CoW) containing identical production schema duplicates for isolated feature testing or rapid CI/CD cycles
- Compute Management — Discover and list explicit compute endpoints (e.g., ep-misty-water-123) to retrieve the exact connection strings required for your application drivers
- Branch Audit — Inspect the execution footprint of specific branches, tracking storage deltas and timeline points (LSN) to understand exactly when a branch split from its parent
- Database Inventory — Enumerate internal SQL database schemas and catalog namespaces mapped inherently to specific branches to guide your connection logic
- Role Management — List and audit PostgreSQL user identities and credential roles capable of querying against specific bounded logical nodes securely
- Resource Provisioning — Initialize fresh serverless workspaces or permanently wipe out entire database ecosystems with irreversible architectural commands
How it works
- Subscribe to this server
- Enter your Neon API Key
- Start managing your serverless Postgres from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Backend Developers — create isolated testing branches and verify database schemas through natural conversation without manual CLI scripts
- Database Administrators — audit compute endpoint resource usage and monitor storage caps across multiple Neon projects directly from your workspace
- Platform Engineers — manage database roles and automate project provisioning efficiently to maintain high-reliability standards
Built-in capabilities (10)
Duplicates Petabytes of PostgreSQL storage instantly using filesystem CoW links, generating an isolated query testing ground tied back directly to the `parent_id` source. Spawn a zero-copy clone (Branch) of a PostgreSQL dataset
Provision an empty Neon Project Serverless Workspace
Destroys all edge-served connection strings, severs active client connections, and completely evaporates physical NVMe-backed storage blocks. Permanently wipe out a complete Neon Postgres ecosystem

Frequently asked questions
What is Neon's 'Zero-Copy Branching' and how do I use it through the agent?
Zero-copy branching allows you to clone a multi-terabyte database instantly using Copy-on-Write (CoW). Use the create_branch tool by providing a parent branch ID. Your agent will trigger the backend to generate an isolated clone in milliseconds, perfect for running migrations or testing features against production-like data.
Can my agent retrieve the exact connection strings for my compute endpoints?
Yes. Use the list_endpoints tool with your Project ID. Your agent will retrieve the explicit hostnames (e.g., ep-misty-water-123.aws.neon.tech) used to actively ingest real query traffic to your serverless Postgres branches.
How do I check the storage consumption for a specific Neon branch?
The get_branch tool retrieves the deconstructed execution footprint of an individual branch. Your agent will report the storage limits and exact number of bytes consumed uniquely by that branch's data delta since it split from its parent.
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 Neon (Serverless PostgreSQL) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
