Tools (6)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

decision.applicable_toGet retrieval/context applicability
Return proposals and canonical decisions whose scope hints or context scope overlap the supplied context/paths. This is retrieval/context applicability only: proposal scope hints are NOT typed-rule applicability (ADR-020) and paths are never glob-evaluated. Read only: this tool never mutates any state and returns no rules or enforcement data. When both inputs are omitted or empty, both match lists are empty.
decision.getGet a proposal or canonical decision
Read one record by stable id. Returns record_type 'proposal', 'canonical_decision', or 'not_found'. Read only: this tool never mutates any state. Use decision.search when you do not already have a stable id.
decision.proposePropose a decision (non-authoritative)
Submit one candidate architectural decision. The proposal enters the Mneme decision index as a non-authoritative proposal with status 'proposed'. This grants NO authority: the proposal is never enforceable and can only become canonical through separate Mneme human authority (D2C), which this MCP does not expose. Repeated identical source/version/content submissions are idempotent. Use decision.propose_batch when submitting multiple candidates.
decision.propose_batchPropose decisions in batch (non-authoritative)
Submit multiple candidate architectural decisions from one producer output. Each candidate receives its own independent proposal identity and enters as a non-authoritative proposal with status 'proposed'. There are no batch acceptance semantics: batch submission grants NO authority, and every proposal remains independently reviewable. Use decision.propose for a single candidate.
decision.searchSearch proposals and canonical decisions
Deterministic text/exact-metadata search. Proposals (lifecycle proposed/accepted/rejected) and canonical decisions (lifecycle active/superseded/deprecated/inactive) are returned in separate lists and never merged. Read only: this tool never mutates any state. Search rank has no enforcement meaning. Use decision.get when you already have a stable id. Within each record domain, all applicable filters combine with AND semantics; proposal-only filters do not exclude canonical results, and vice versa.
decision.traceTrace decision lineage
Return the deterministic lineage actually known for a proposal id or canonical decision id. The result_type is explicit (proposal_trace / canonical_trace / trace_not_found); unresolved ids stay type-unknown. Read only: this tool never mutates any state. Canonical rule-lineage integrity failures fail closed as protocol errors and are never returned as partial traces. Use decision.get for the record alone; use decision.trace when you need provenance, acceptance, rule, or declared-evidence lineage.
