# /sse stops working

Calls to /sse on Sentry MCP stopped working on October 28, 2025.

On October 28, 2025, the /sse endpoint will be removed and calls to it will fail. Sentry MCP announced that the SSE transport endpoint is no longer supported.

## What to use instead

Connect to the /mcp endpoint on mcp.sentry.dev over Streamable HTTP instead.

- API: Sentry MCP (mcp.sentry.dev)
- Kind: Endpoint removal

## Sentry MCP's words
