Database and app builderIndependent review. IonBin has no partnership with Neon and was not paid for this page. Our evaluation is our own, based on public documentation and our research. Product names are trademarks of their owners and are used for identification only. How disclosure works.
Serverless Postgres with branching and a free plan. Neon's MCP server can manage projects and run SQL, offers a read-only mode, and has an official Claude connector.
Best for
- Developers who want a Postgres database an AI client can query
- Testing schema changes on a branch first
Not for
- Production databases connected with write access and no review
- Non-technical teams needing a spreadsheet-style app
Top use cases
- Ask an AI client to run a read-only SQL query source ↗
- Create a branch to test a schema change source ↗
- List projects and databases in an account source ↗
In depth
MCP server
Neon hosts its MCP server at https://mcp.neon.tech/mcp, using OAuth or an API key. Adding ?readonly=true limits it to read-only tools, and a project-scoped mode narrows access further. An official Claude connector is listed. Checked 2026-10-18. source ↗
Plans
Free costs $0. Launch is usage-based at $0.106 per compute-unit hour and $0.35 per GB-month. Scale is $0.222 per compute-unit hour. Checked 2026-10-18. source ↗
How to use it with AI
How Neon connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.
| Platform | MCP / connector | API (agent-written code) | Browser | Upload / export |
|---|---|---|---|---|
| Claude (incl. Claude Code) | Not documented Official Claude connector. A named plugin, skill or CLI does not by itself establish an MCP/native connector pairing. Verify the route and client setup. Neon named integration docs ↗Claude (incl. Claude Code) MCP docs ↗ | Not documented Claude (incl. Claude Code): Claude Code edits files and runs commands Neon publishes an API, but this pairing still needs network, authentication and execution-scope checks. Neon API ↗Claude (incl. Claude Code) docs ↗ | Inferred Claude Code with the Claude in Chrome extension (Chrome, Edge and other Chromium browsers). Neon is a web app; the pairing itself is not documented. Claude (incl. Claude Code) browser docs ↗ | Not documented Verify which side exports and which imports, supported formats and permissions. Neon's recorded upload/import status is to-verify; Claude (incl. Claude Code)'s file status is yes. These flags do not establish a file-transfer route. Claude (incl. Claude Code) file docs ↗ |
| OpenAI Codex | Not documented Neon has an official MCP server and OpenAI Codex supports MCP, but Neon's docs don't name this pairing. Auth setup may differ.

Confirmed is reserved for evidence of the specific connection route. The current named integrations include plugins, skills and CLIs, so a named platform alone does not confirm MCP or a native connector. Inferred means each side documents a relevant capability, but no document describes the pairing. Code execution still needs network and credential access; file handling still needs a compatible format and transfer direction. Not documented means the records do not establish the route. IonBin has not tested these pairings. Recorded Oct 18, 2026.

Connection capabilities to compare
An official MCP server is documented for this tool. These platforms separately document MCP client support: ChatGPT, Claude, Cursor, Gemini (Google), Google Antigravity, Grok, Grok Bot, Lindy, LM Studio, Mistral Vibe, OpenAI Codex. This inventory does not establish compatible transport, authentication or actions for a pairing. Check the connection matrix and linked sources.
Automation hubs to assess for a custom API connection: Gumloop, Make, n8n, Zapier. Verify credentials, supported requests, limits and error handling; no configured integration is implied.
