• Grade MCP tool definitions for agent-readiness

  grade_tools

  Grade MCP tool definitions (the tools array from a tools/list result) for how well AI agents can pick and call them. Returns a 0–100 score and A–F grade, per-tool scores, and findings with concrete fixes: missing or weak descriptions, untyped parameters, strings without maxLength, missing required or additionalProperties, missing annotations (readOnlyHint, destructiveHint …), invalid or duplicate names, outputSchema and enum problems, hidden characters and tool-poisoning patterns. Also returns an ESTIMATED token cost of the definitions (characters ÷ 4; real counts vary by model). Pure parsing: no network calls, and your tool definitions are never stored. Read-only. Same engine as the ToolGrade JSON API (POST /api/grade).
