N Memory
UnclaimedMemory your agent can trust — every answer carries its source; when it doesn't know, it says so. Hermetic, local, MCP.

Claimed and verified servers get a weekly static scan that shows what the code can reach: external services, environment variables, shell commands, agent configuration folders, plus any dependencies with known advisories. Claim this listing to get one. How the security profile works
22 of 22 tools
Documented tools (22)
From project documentation. A server handshake does not verify each tool’s description or behavior.
memory_alias
teach recall synonyms the store then honors
memory_bootstrap
cold-start pack: your constraints FIRST (never capped), the one next action, decisions, traps — in ≤1500 tokens
memory_classify
kind / scope / authority / taint labels; optionally persisted as a sidecar
memory_consolidate
deterministic maintenance plan: exact dupes, merge proposals, tier moves
memory_digest
session-start projection: what you know, what's ready, what's blocked.
memory_export
the whole store as one deterministic markdown view; byte-identical on an unchanged store
memory_extract
text → candidate memories over the closed 10-kind set; advisory, stores nothing
memory_forget
tombstones with audit, never silent deletion.
memory_get
one full capsule by id, with GET-only fact time, relations,
memory_import
one-shot import of native sources (CLAUDE.md, AGENTS.md, memory dirs); born tainted
memory_ingest
capture with a birth certificate: no source + anchor, no storage.
memory_list
compact index with project fences
memory_merge
reconcile a second store file into this one: content-hash identity, id-remap, forget-wins, deterministic — the offline-first path to keep two machines' stores in sync
memory_outcome
record an observed consequence (advisory observation, never a self-certified close)
memory_pin
pin (or unpin) a load-bearing capsule: decay-exempt + archive-vetoed, surfaced as a pinned flag and digest section; NEVER eligibility (fenced capsules stay fenced, taint dominates pin)
memory_preference
pairwise preference evidence (chosen-over, in context, by whom)
memory_relate
the five edges you reach for daily, out of nine declared: supersedes, derivedfrom, witnesses, blocks, and falsifies (a disproven fact stops grounding recall, but the evidence stays). The other four — proposes, partof, groundedin, about — are in the tool surface below.
memory_retrieve
recall as evidence: grounded, missingevidence, or an honest abstain.
memory_session_start
/ memorysessionfinish — bracket a session; finish captures the handoff the next session's digest leads with
memory_vector
attach caller-fed embeddings (optional cosine lane; no embedder inside)
memory_visual
deterministic Mermaid projections (dag / relations / tiers / sessions), plus an MCP Apps view
topic_id
on memoryretrieve — fence recall to one topic: the capsules

FAQ
Questions about N Memory MCP Server
- How do I connect N Memory MCP Server to Claude?
- The listing records `claude mcp add nmemory -- "$(pwd)/target/release/nmemory" --project my-project` as its setup step. Run it, then follow the repository's instructions for the client configuration; the listing names Claude Code as compatible clients.
- Is N Memory MCP Server free?
- The listed licence is AGPL-3.0. Check the upstream terms for permitted use and commercial requirements; a public repository does not by itself mean the software is free or open source. Connected APIs and hosted services may have separate charges.
- What can N Memory MCP Server do?
- N Memory MCP Server documents 22 tools to the agent, including memory_alias, memory_bootstrap, memory_classify. The descriptions above come from project documentation. A live handshake does not test individual tool behavior.
