Neon MCP server

The Neon MCP server gives AI agents control of Neon serverless Postgres: create projects and branches, run SQL, inspect schemas, find slow queries and run migrations on a branch before applying them.

Connect Neon

One-step setup for Cursor, VS Code and Claude Code (creates an API key and configures the editor)

Terminal
npx neon@latest init

Add the hosted server with OAuth to every detected agent

Terminal
npx add-mcp "https://mcp.neon.tech/mcp?category=projects&category=branches&category=endpoints&category=querying&category=schema"

Any client with a JSON config, read-only

Config
{"mcpServers": {"Neon": {"url": "https://mcp.neon.tech/mcp?readonly=true"}}}

OAuth opens a browser window to authorize your Neon account; for an organization's projects, name the org_id or project_id in your prompt. With an API key, send it as Authorization: Bearer. If IP Allow is on, allow 34.192.103.46 and 23.22.233.166.

What the Neon MCP server does

The Neon MCP server connects an AI agent to Neon, the serverless Postgres service that is now part of Databricks and built on its Lakebase Postgres. The agent can list and create projects, create, reset and delete branches, manage compute endpoints and snapshots, run SQL or a transaction, list tables and describe their schemas, and get a connection string. It also covers newer Neon products such as Neon Auth, the Data API, functions and storage.

Neon's server builds on database branching for safer changes. A migration tool first applies a schema change on a temporary branch so the agent can test it, then a second tool applies it to the main branch once you agree. A similar pair finds slow queries, tests tuning such as new indexes on a branch, and then applies the result. Other tools explain query plans and compare schemas between branches.

Neon hosts the server at mcp.neon.tech with OAuth or an API key, and URL parameters limit it to read-only tools, one project or chosen tool categories. Neon says the server is meant for local development and IDE use and does not recommend it for production. The GitHub repo had 648 stars on 2026-10-01.

Tools it gives your agent

  • list_projects
  • create_project
  • create_branch
  • describe_branch
  • run_sql
  • run_sql_transaction
  • get_database_tables
  • describe_table_schema
  • list_slow_queries
  • explain_sql_statement
  • prepare_database_migration
  • prepare_query_tuning

When to use Neon

  • You want the agent to spin up a fresh Postgres database for a prototype in one prompt.
  • You want schema migrations tested on a branch before they touch your main database.
  • A query is slow and you want the agent to find it and try an index safely.
  • You want a summary of all your Neon projects and what each one holds.

When to pick something else

  • Production databases: Neon itself advises against using the MCP server there, because it can create, change and delete projects and branches.
  • Other Postgres hosts: it manages Neon accounts through the Neon API, not any Postgres server.

What Neon needs

  • A Neon account (OAuth) or a Neon API key
  • Node.js 18 or newer for the npx setup commands

Questions people ask

Is the Neon MCP server free?

Yes. The server is open source and costs nothing; your Neon usage is billed as normal, and Neon has a Free plan (pricing page, 2026-10-01).

Can the Neon MCP server delete things?

Yes, with write access it can delete projects and branches. Connect with ?readonly=true or untick Allow writes during sign-in to keep it to read-only tools.
