How to Rotate an MCP Endpoint URL
Leaked mcp.json, Slack paste, or someone left the company? Rotate the Synra MCP endpoint, update Cursor/Claude/ChatGPT, and check Usage — without changing your database password.

Use AI and Your Database for Customer Support Questions
Support shouldn't wait on engineering for 'when did they cancel?' Point Claude or ChatGPT at a safe read-only connection — prompts, table allowlists, and what never to put in a ticket reply.
