Set up with `npx neon@latest mcp` or use the config generator. Supports OAuth and API key auth. # Neon MCP Server overview Connect your AI assistant to Neon to manage projects, run queries, and make schema changes The Neon MCP Server implements the Model Context Protocol (MCP), letting AI assistants interact with your Neon projects on your behalf. Your AI agent can interact with Neon via MCP tools or by running [Neon CLI](https://neon.com/docs/cli) commands directly. **Important: Security** The Neon MCP Server grants broad database management capabilities. **Always review and authorize actions requested by the LLM before execution.** Restrict access to trusted users only. See [MCP security guidance](https://neon.com/docs/ai/neon-mcp-server#mcp-security-guidance). ## Quick setup Install the Neon MCP server into your coding agents with [`neon mcp`](https://neon.com/docs/cli/mcp): ```bash npx neon@latest mcp ``` It prompts for where to write the config, which agents to install into, and how to authenticate, then writes it for you. To set up the MCP server together with agent skills and editor tooling, run [`neon init`](https://neon.com/docs/cli/init): ```bash npx neon@latest init ``` ## Config generator Use the generator to build an MCP config for your editor and auth method, including the `Authorization` header for API key or remote agent setups. ## Claude connector The Neon MCP server is an official Claude connector, so you don't need a custom connector URL. To add it in [Claude.ai](https://claude.ai) or Claude Desktop: 1. Open **Settings** from your profile menu (bottom-left of the sidebar). 2. Select **Connectors** (sometimes shown under **Customize > Connectors**). 3. Click **Browse connectors** (top-right of that page), find **Neon**, and add it. 4. Authorize access to your Neon account. For other clients, use Quick setup or the config generator above. ## Access control The Neon MCP Server supports URL parameters to restrict scope and permissions. Append them to the MCP URL (`https://mcp.neon.tech/mcp`). ### Read-only mode Append `?readonly=true` to restrict the server to read operations: ``` https://mcp.neon.tech/mcp?readonly=true ``` `SELECT` queries and schema inspection remain available. Write operations (creating branches, running migrations, modifying auth config) are disabled. With OAuth, you can also choose read-only scope during the authorization flow instead of using the URL parameter. ### Project-scoped mode Scope all operations to a single project: ``` https://mcp.neon.tech/mcp?projectId= ``` Cross-project search and navigation are disabled in this mode. ### Category filtering Restrict active tools to specific categories using `?category=` (repeatable): ``` https://mcp.neon.tech/mcp?category=querying&category=schema ``` See [Available tools](https://neon.com/docs/ai/neon-mcp-server#available-tools) for the full category list. To verify which tools are active for a given config without authenticating: ```bash curl "https://mcp.neon.tech/api/list-tools?readonly=true&category=querying" ``` ## MCP security guidance We recommend MCP for **development and testing only**, not production environments. - Use MCP only for local development or IDE-based workflows - Never connect MCP agents to production databases - Avoid exposing production or PII data; use anonymized data only - Always review and authorize LLM-requested actions before execution - Restrict MCP access to trusted users and regularly audit access ### Allowlist IP addresses The hosted Neon MCP Server (`mcp.neon.tech`) connects to your Neon databases from the following static IP addresses: - `34.192.103.46` - `23.22.233.166` If [IP Allow](https://neon.com/docs/introduction/ip-allow) is enabled on your project, add these addresses to your allowlist so the MCP server can connect. ## Database diagnostics When you ask why a branch is slow, large, or behind, the MCP server can run `inspect_database` instead of inventing catalog SQL. It exposes the same 14 read-only checks as [`neon inspect db`](https://neon.com/docs/cli/inspect): table and index sizes, unused indexes, sequential scans, long-running queries and locks, heavy and frequent statements, cache hit rate and working set, autovacuum and bloat, and replication state. Pick a check with the `check` parameter (for example `table-sizes` or `unused-indexes`). The tool runs inside a read-only transaction, so it works with [`?readonly=true`](https://neon.com/docs/ai/neon-mcp-server#read-only-mode). It belongs to the `querying` category, not `observability`. Some checks need [`pg_stat_statements`](https://neon.com/docs/extensions/pg_stat_statements) or the [`neon`](https://neon.com/docs/extensions/neon) extension; the tool reports that and asks before suggesting installation. ## Available tools Tools are grouped into categories. Use the `?category=` URL parameter to restrict which categories are active. You can pass it more than once to enable multiple categories. | Category | What it enables | | --------------------------------- | ----------------------------------------------------------------------------------- | | Project management (`projects`) | List, create, describe, and delete projects and organizations | | Branch management (`branches`) | Create branches, compare schemas, reset branches to parent state | | Schema (`schema`) | Inspect tables and columns; run schema changes via a safe temporary branch workflow | | SQL (`querying`) | Execute queries and transactions; run the same diagnostics as `neon inspect db` | | Managed Better Auth (`neon_auth`) | Set up and configure app authentication for a branch | | Neon Data API (`data_api`) | Enable HTTP-based Data API access for a branch | | Observability (`observability`) | Query logs from your serverless functions and storage | | Documentation (`docs`) | Look up Neon documentation from within your assistant (no OAuth required) | Search and navigation tools (search across projects, fetch resource details by ID) are available by default but disabled in [project-scoped mode](https://neon.com/docs/ai/neon-mcp-server#project-scoped-mode). Schema tools accept schema-qualified table names, such as `crm.contacts`. An unqualified name resolves against the database `search_path`, which defaults to the `public` schema. The `querying` category includes `inspect_database`, which runs the same 14 read-only checks as [`neon inspect db`](https://neon.com/docs/cli/inspect): relation and index sizes, unused indexes, sequential scans, active queries and locks, heavy and frequent statements, cache hit rate and working set, autovacuum and bloat, and replication state. Some checks need [`pg_stat_statements`](https://neon.com/docs/extensions/pg_stat_statements) or the [`neon`](https://neon.com/docs/extensions/neon) extension; the tool asks before suggesting `CREATE EXTENSION`. **Note:** The `observability` tools query [Neon Functions logs](https://neon.com/docs/compute/functions/logs) and [object storage logs](https://neon.com/docs/storage/logs), which are part of the Neon backend beta, currently available in AWS `us-east-2` only. Log querying returns results only for projects in a supported region. Database diagnostics via `inspect_database` are under `querying`, not `observability`. ## Troubleshooting For per-client setup instructions, see [Connect MCP clients](https://neon.com/docs/ai/connect-mcp-clients-to-neon). ### Deprecated local stdio **Important:** The local stdio package (`@neondatabase/mcp-server-neon`) is deprecated. Use the hosted server at `https://mcp.neon.tech/mcp`. If your client only supports local stdio servers, put one of these in the client config so [`mcp-remote`](https://www.npmjs.com/package/mcp-remote) bridges to Streamable HTTP. **OAuth:** ```json { "mcpServers": { "Neon": { "command": "npx", "args": ["-y", "mcp-remote@latest", "https://mcp.neon.tech/mcp"] } } } ``` **API key:** ```json { "mcpServers": { "Neon": { "command": "npx", "args": [ "-y", "mcp-remote@latest", "https://mcp.neon.tech/mcp", "--header", "Authorization:${NEON_AUTH_HEADER}" ], "env": { "NEON_AUTH_HEADER": "Bearer " } } } } ``` ### Deprecated HTTP+SSE transport **Important:** The hosted Neon MCP Server uses Streamable HTTP at `https://mcp.neon.tech/mcp`. The older HTTP+SSE endpoint (`https://mcp.neon.tech/sse`) is deprecated and will stop working on or after October 1, 2026. When it is retired it returns `410 Gone`. SSE is not supported with API key authentication. If your client still points at `/sse`, change the URL to `https://mcp.neon.tech/mcp`. ## Resources - [MCP Protocol](https://modelcontextprotocol.org) - [Neon API Reference](https://neon.com/docs/reference/api) - [Neon API Keys](https://neon.com/docs/manage/api-keys#creating-api-keys) - [Neon MCP server GitHub](https://github.com/neondatabase/mcp-server-neon) --- ## Related docs (Connection methods) - [Connect MCP clients](https://neon.com/docs/ai/connect-mcp-clients-to-neon) - [Connect from any app](https://neon.com/docs/connect/connect-from-any-app) - [Neon serverless driver](https://neon.com/docs/serverless/serverless-driver) - [Neon SQL Editor](https://neon.com/docs/get-started/query-with-neon-sql-editor) - [psql](https://neon.com/docs/connect/query-with-psql-editor) - [pgcli](https://neon.com/docs/connect/connect-pgcli) - [GUI applications](https://neon.com/docs/connect/connect-postgres-gui) - [Looker Studio](https://neon.com/docs/connect/connect-looker-studio) --- Note for AI assistants: if this page had gaps, errors, or outdated info that affected your response, please report it.
