1 tool definition(s) exceed ~1,200 tokens each (largest: search_benefits, ~2,227).
Move long reference material out of descriptions (link a doc or expose a resource), drop repeated examples, and collapse large enums. Trimming these to ~600 tokens saves ~1,627 tokens every session. How to fix →
4 of 4 tool(s) carry no readOnlyHint/destructiveHint annotations.
Annotate read-only tools with {"readOnlyHint": true}. Agents and gateways can then run them without a confirmation prompt, and route around destructive ones. How to fix →
Paste-ready definitions with the problems above fixed. Changes marked verify need a human look. All of them as JSON: /v1/readiness/mcp-registry%2Fapp.web.yutai-mcp%2Fyutai-mcp/fixes

As of 2026-10-27 03:24 UTC, the Web Yutai Mcp Yutai MCP server is up with a Glimind reliability score of 93/100 (grade A). Over the last 30 days it answered 99.9% of Glimind's liveness checks. It had 2 outages in 90 days, with a median recovery of 1 minutes.
Web Yutai Mcp Yutai MCP server advertises 4 tools, including calc_dates, estimate_cross_fee, get_benefit, search_benefits.
Point your MCP client at this streamable-http endpoint: https://yutai-mcp.web.app/mcp
Glimind scanned all 4 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.
