Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • analyze_session_usage

    Track which tools are actually called vs loaded in a session. Register tools, log calls, and generate waste reports showing unused tools ranked by token cost.

  • audit_context_budget

    Analyze the token cost of MCP tool definitions. Estimates tokens per tool using chars/4 on the full JSON definition. Returns per-tool costs and percentage of common context windows.

  • compress_schema

    Compress a verbose tool schema to reduce token usage. Light: remove short descriptions. Medium: shorten descriptions, remove examples. Aggressive: strip all descriptions.

  • get_optimization_report

    Full context window health check combining audit, removal suggestions, and compression recommendations. Returns an executive summary with health grade and projected savings.

  • health_check

    Returns server health, uptime, version, and storage stats

  • optimize_tool_loading

    Given a task description, recommend the minimal set of tools needed. Uses keyword matching and category relevance scoring to rank tools.

  • suggest_removals

    Identify tools that can be removed based on usage history. Scores: never_used > not_used_30_days > rarely_used. Returns removal candidates with estimated token savings.
