signals-scout-mcp-tool-calls

Signals scout for PostHog MCP tool calls. Watches $mcp_tool_call telemetry for tools that need improvement — broad-reach failure rates, retry hammering, slow or context-bloating responses — grouped by owning product category, each with a fix suggestion.

Compatibility

PostHog Signals agent (Claude sandbox). Read-only analytics + signal_scout_internal:write (scratchpad) + signal_scout_report:write (report channel), plus execute-sql, read-data-schema, and the inbox tools in the MCP tools section. The SQL cookbook lives in references/queries.md and the dashboard recipe for the recorded metrics in references/metrics-dashboard.md (read both on demand); deep-dives into posthog:exploring-mcp-tool-quality and posthog:querying-posthog-data.
