Use trace-mcp through bb to search indexed code and recall project decisions with compact context.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Use `trace_get_index_health` to check the index, then `trace_search` to find symbols before reading whole files. Use `trace_get_symbol` for an exact definition and `trace_get_outline` for file structure. Use `trace_get_project_memo` at the start of a task when prior decisions matter, `trace_query_decisions` for a focused recall query, and `trace_remember_decision` to record an explicit English-language decision with the current bb thread as its session ID. Automatic decision capture rejects non-English text; for a manually entered decision in another language use the panel or `bb trace remember`. For other capabilities, search the catalog with `trace_tools` and pass the selected tool name and arguments to `trace_call`. The thread's **Trace context** panel shows index health, saved decisions, and the provider's context-window usage. The same data and explicit writes are available through `bb trace status`, `bb trace decisions`, `bb trace remember`, and `bb trace index`; pass `--thread <id>` outside a bb thread. …

How to install
mdr add nikolai-vysotskyi/trace-mcp/trace-mcp@sha256:4fc3208544e9a103The line at the top of this page pins the label git:20261009.31ebfd7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
