What to fix (3)

51 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 →

30 parameter(s) across 7 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: list_observability_events, list_overage_charges, list_rightsize_recommendations, list_subscription_history, list_tool_execution_logs and 2 more

Requires authentication (Bearer); tool definitions could not be read anonymously.

If discovery should be public, allow initialize + tools/list without credentials and gate only tools/call. Directories and routers can then list your tools.

Is the Kaicalls MCP server safe to connect to an AI agent?

Glimind scanned all 51 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.
