Discussion: We analyzed 78,849 MCP tool descriptions. 98% don't tell AI agents when to use them.

Saw an interesting discussion on r/MCP about this — wanted to bring it here. **Original topic:** We analyzed 78,849 MCP tool descriptions. 98% don't tell AI agents when to use them. > Follow-up to our \[State of MCP Security report\](https://spiderrating.com/blog/state-of-mcp-security-2026) (thanks for all the great feedback on that one). We dug deeper into the description quality data. Turns out the biggest problem in the MCP ecosystem isn't security — it's documentation. \*... What are your thoughts? Has anyone here dealt with MCP server? --- *Discuss more at [0n MCP](https://www.0nmcp.com) — the hub for [agentic workflow engine](https://www.0nmcp.com).*
