# /sse stops working

Calls to /sse on Neon MCP stopped working on October 1, 2026.

## What to use instead

Connect to https://mcp.neon.tech/mcp over Streamable HTTP; SSE never took an API key.

- Kind: Endpoint removal
- Announced: July 25, 2025
- Takes effect: October 1, 2026
- Calls after that day: fail
- Calls it hits: `/sse`

## Neon MCP's words

> 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.
