Cartographer MCP tools (5, 1 write)
write = sends, deletes, buys or postsRead from the package source without running it. The installed server may list more.
evaluate_redundancyCompare draft source code to indexed capability chunks and report high-similarity reuse candidates.
map_dependenciesReturn dependency edges for a chunk key so agents can assess import chain and portability.
reindexwrite actionRun full/incremental reindex for selected paths. Uses parser + atomic file upsert; intended for controlled refresh jobs.
search_capabilityFind reusable capability chunks by semantic intent under deterministic policy gates (trust, density, import strictness, telemetry).
set_policy_profileSet active policy profile for the current MCP server process/session.
