Tools & Capabilities Breakdown

Perfetto MCP Rs Tools (17)

load_trace

Open one trace with `path`, or several with `paths`; returns an opaque `trace_id` and lightweight routing summary for each file (type/profile, duration, platform, process/thread counts, capabilities, redaction policy, recommended next tools)

execute_sql

Run a PerfettoSQL query (max 5000 returned rows). Prefer the dedicated `chrome_*` / `list_*` tools for standard analyses; use this for custom joins or aggregations they don't expose. Output shaping: `head`/`limit`, `summary`, `columns_only`, `include_row_count`, `max_string_len`. Sensitive URL/head…

list_tables

List tables/views in the loaded trace, optional GLOB filter

list_table_structure

Show column names and types for a table

list_processes

List processes (pid, name, start/end timestamps)
