What is the NMEMORY MCP Server?

Hermetic local memory for coding agents: provenance-mandatory capture, honest recall, zero sockets.

What the server does

Your coding agent forgets you between sessions, so you spend every morning re-explaining decisions it was there for. Bolt a memory onto it and you usually trade that for something worse: asked a question it has nothing solid for, the memory hands back something plausible anyway, and your agent goes and edits your code with it.

Recorded tools

Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.

ToolWhat it does
memory_ingestcapture with a birth certificate: no source + anchor, no storage.
memory_retrieverecall as evidence: grounded, missing_evidence, or an honest abstain.
memory_digestsession-start projection: what you know, what's ready, what's blocked.
memory_relatethe five edges you reach for daily, out of nine declared: supersedes, derived_from, witnesses, blocks, and falsifies (a disproven fact stops grounding recall, but the evidence stays). The other four — proposes, part_of,
memory_forgettombstones with audit, never silent deletion.
memory_extracttext → candidate memories over the closed 10-kind set; advisory, stores nothing
memory_classifykind / scope / authority / taint labels; optionally persisted as a sidecar
memory_importone-shot import of native sources (CLAUDE.md, AGENTS.md, memory dirs); born tainted
memory_getone full capsule by id, with GET-only fact time, relations,
memory_listcompact index with project fences
memory_bootstrapcold-start pack: your constraints FIRST (never capped), the one next action, decisions, traps — in ≤1500 tokens
memory_aliasteach recall synonyms the store then honors
memory_vectorattach caller-fed embeddings (optional cosine lane; no embedder inside)
memory_visualdeterministic Mermaid projections (dag / relations / tiers / sessions), plus an MCP Apps view
