What to fix (9)

Loading this server's tool list costs an agent ~79,275 tokens before any work — more than 100% 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.

1 tool definition(s) exceed ~1,200 tokens each (largest: create_organization_proposal_activity, ~1,458).

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 ~858 tokens every session.

Tools: create_organization_proposal_activity · saves ~858 tokens/session

414 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.

657 parameter(s) across 181 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.

Tools: accept_dispatch_arrangement, act_activity_raffle, analyze_cooperation, apply_organization_to_alliance, apply_to_organization and 176 more

1 tool(s) have descriptions under 20 characters.

Say when to use the tool and what it returns, not just its name restated ("Get weather" → "Current weather for a city: temperature, conditions, wind. Use for 'now', not forecasts.").

Tools: get_cooperation_share_access

Reachable 98.5% of the time over the last 30 days; median recovery 7 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.

Handshake + tools/list takes ~3,898 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: 2 tool(s) removed and 73 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.

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.

Get alerted

Get an email or webhook when this server's readiness drops by 10+ points, tool-poisoning text appears, or a tool breaks:

curl -X POST https://glimind.com/v1/subscriptions -H 'content-type: application/json' -d '{"tools":["mcp-registry/io.github.yzlee/opcmenu"],"email":"[email protected]"}'

Agents: watch_tool({"toolId": "mcp-registry/io.github.yzlee/opcmenu"}) over MCP.

Is the Yzlee Opcmenu MCP server safe to connect to an AI agent?

Glimind scanned all 414 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.
