Third-party server, listed as discovered. Review its source before installing.
Loading this server's tool list costs an agent ~68,911 tokens before any work — more than 99% of MCP servers.
Split rarely-used tools into a separate server or a toolset the client can enable, or expose one "search tools" entry point. Many agents load every connected server's tools into every request. How to fix →
214 tools on one server. Tool-selection accuracy drops as the menu grows, and some clients (e.g. Cursor) cap the number of active tools.
Group tools by task into smaller servers or toolsets, and merge near-duplicates behind one tool with a mode parameter. How to fix →
2328 parameter(s) across 212 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 →
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 →
Handshake + tools/list takes ~2,213 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.
In the last 30 days: 6 tool(s) removed and 19 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 →
No tool declares an outputSchema.
Declare outputSchema and return structuredContent (MCP 2025-06-18+). Agents can then parse results without guessing, and chain tools reliably. How to fix →
2 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 →
Paste-ready definitions with the problems above fixed. Changes marked verify need a human look. 200 tool(s) still need parameter descriptions written by someone who knows the API. All of them as JSON: /v1/readiness/mcp-registry%2Fxyz.558686.gpt55%2Ftoken-gateway/fixes

As of 2026-10-20 11:16 UTC, the 558686 Gpt55 Token Gateway MCP server is up with a Glimind reliability score of 83/100 (grade B). Over the last 30 days it answered 99.8% of Glimind's liveness checks. It had 68 outages in 90 days, with a median recovery of 4 minutes.
558686 Gpt55 Token Gateway MCP server advertises 214 tools, including chat_gpt_5_5, chat_gpt_5_6_soul, chat_gpt_5_6_terra, gpt55_answer, gpt55_answer_mini.

Glimind scanned all 214 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.
