memcp@0.1.0
CAUTION· not startedPublisher claims: "Gives AI agents a durable, locally hosted temporal memory built from a markdown vault you own, exposing hybrid semantic/lexical/entity search over events, threads, transcripts, entity relationships with validity dates, and patterns with confidence decay. Writes are approval-gated, so agents can draft, commit, and sync new memories while keeping every index rebuildable and nothing leaving your machine." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Not started: dependency install failed; the server itself was not observed.- Tested
- the dependency install step · every file read, file written and host contacted by what ran
- Not tested
- server startup · the tool list · tool behavior
What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.
Before you give it your token
- It will ask for
HF_TOKENMEMCP_PG_DSNPGPASSWORDConfiguration, not credentials: HF_HOME, MEMCP_DATA, MEMCP_MIGRATIONS_DIR, MEMCP_OWNER, MEMCP_REPO, MEMCP_SELF_THREAD, MEMCP_VAULT, MODEL_TIER, PGDATABASE, PGHOST, PGPORT, PGUSER, TN_AUTO_REBUILD, TN_AUTO_REBUILD_INTERVAL, TN_AUTO_REBUILD_MIN_INTERVAL, TN_CALL_LOG, TN_INCLUDE_FIXTURES, TN_INDEX_DEVICE, TN_INDEX_ROOTS, TN_MIGRATIONS_DIR, TN_RERANK_MODEL, TN_ROUTING_BOOST, TN_ROUTING_BOOST_MODE- Where it talks to
- no vendor host named in the code
- What the honeypot saw
- no credential files read · no network
- What we could not test
- server startup · the tool list · tool behavior
Connect it with a scoped credential, under the guard. It asks for HF_TOKEN, MEMCP_PG_DSN, PGPASSWORD and talks to its vendor. Give the credential to the guard, not the server: the value never enters the server's environment and only travels to the host you bind. What the tools do with a real credential was not observed.
Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-13 and scored it 71/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; HTML comment carrying imperative instructions to the agent; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
