- Managing and querying Perfetto traces using the trace_processor MCP server.
# Trace Processor
The `trace_processor` extension launches a long-running FastMCP server wrapping
Perfetto's trace processor capabilities, allowing seamless interaction with
trace files (`.pftrace`, `.perfetto-trace`, `.pb`).
## Writing PerfettoSQL and Schema Analysis
For comprehensive guidance on querying traces, utilizing standard library
modules, and schema structures, refer directly to the native Perfetto AI skills
inside `third_party/perfetto/ai/skills`:
- **Querying Traces**: See the
[perfetto querying traces](/third_party/perfetto/ai/skills/perfetto/infra-references/querying.md)
skill.
- **Common SQL Tables**: Explore standard table definitions such as `slice`,
`thread`, `process`, `sched_slice`, and `track`.
- **Perfetto Standard Library**: Utilize standard library modules like
`slices.with_context` by starting queries with `INCLUDE PERFETTO MODULE`.
