Config index

Every key the config schema accepts, in schema order, with its type and the default that applies when you leave it out. It is generated from the schema itself, so an option cannot ship without appearing here.

This page answers “does this key exist, and what is it set to if I say nothing”. For what a key is for — and for the sections large enough to have earned their own page — start at configuration, which links on to quality gates, telemetry, daemon memory and decision memory.

Everything is optional: trace-mcp indexes a standard project with no config file at all. A default of — means the key is a section rather than a value; _unset_ means there is no default and the feature reads the key only when you supply it.

One key is worth reading with care: db.path is vestigial. Nothing reads it. The index location is not configurable — getDbPath() in src/global.ts puts every project’s database under ~/.trace/index/. The key is still accepted so existing config files keep validating, and will be dropped in the next major.
