What to fix (6)

Reachable 92.5% of the time over the last 30 days; median recovery 12 min.

Agents fail over to an alternative the first time a call fails. Add health checks and restart-on-failure, and avoid cold starts on serverless hosts.

33 parameter(s) across 12 tool(s) have no description.

Add a "description" to each parameter with its format and an example ("ISO 8601 date, e.g. 2026-10-17"). This is the commonest cause of wrong arguments on the first call. How to fix →

Tools: deliverable_acceptance_read, deliverable_acceptance_submit, history_private_jobs_detail, history_private_jobs_export, history_private_jobs_list and 7 more

4 tool(s) have parameters with no type (no type/enum/anyOf/$ref).

Give every parameter a "type" (or "enum"/"anyOf"). Untyped parameters make models guess — strings for numbers, objects for arrays. How to fix →

Tools: draft_check, evidence_draft, evidence_procurement, research

Handshake + tools/list takes ~2,125 ms.

Serve tools/list from memory, keep the process warm, and host close to your users. Every new agent session pays this before its first call.

6 tools share an identical description with another tool on this server.

Make each description say how the tool differs from its siblings, or the model will pick between them at random. How to fix →

Tools: history_export, history_owned_read, history_private_jobs_detail, history_private_jobs_list, run_owner_export and 1 more

In the last 30 days: 0 tool(s) removed and 8 schema change(s).

Add new tools or optional parameters instead of renaming or removing; deprecate first (say so in the description) and remove later. Agents cache tool contracts. How to fix →

Auto-fix: 4 corrected tool definitions

Paste-ready definitions with the problems above fixed. Changes marked verify need a human look. 12 tool(s) still need parameter descriptions written by someone who knows the API. All of them as JSON: /v1/readiness/mcp-registry%2Fio.github.tang-vu%2Fkeryx/fixes

Is the Tang Vu Keryx MCP server safe to connect to an AI agent?

Glimind scanned all 25 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.
