loom@0.1.3
VERIFIED· startup onlyPublisher claims: "Portable MCP server for storing, searching, and verifying compressed LLM context without losing invariants." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
Coverage
Startup only; authenticated tool behavior not tested.- Tested
- server startup over stdio (initialize sent) · every file read, file written and host contacted by what ran
- Not tested
- the tool list (the server exited before answering) · what the tools do when called with real credentials
What this means for the label: Verified 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
LOOM_DB_PASSWORDConfiguration, not credentials: LOOM_ALLOWED_DIRS, LOOM_AUDIT_DIR, LOOM_AUTO_STORE_THRESHOLD, LOOM_BURST, LOOM_DASH_PORT, LOOM_DB, LOOM_EMBED_MODEL, LOOM_HOST, LOOM_LOG_LEVEL, LOOM_MAX_FILE_MB, LOOM_PORT, LOOM_PROFILE, LOOM_RATE_LIMIT, LOOM_REDACT, LOOM_RPM, LOOM_SESSION_ID, LOOM_STORE_CMD, LOOM_TRANSPORT, LOOM_TTL_DAYS, LOOM_VECTORS- Where it talks to
- no vendor host named in the codeAlso astral.sh, owasp.org — not the publisher's domain; check what for before connecting.
- What the honeypot saw
- no credential files read · no network
- What we could not test
- the tool list (the server exited before answering) · what the tools do when called with real credentials
Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names astral.sh, owasp.org as well as its own vendor. The guard injects LOOM_DB_PASSWORD only into requests to the host you bind (and its subdomains) and refuses the rest.
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; startup only; authenticated tool behavior not tested) on 2026-11-11 and scored it 83/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.

Tokens estimated at four characters each. The tool list is re-read by the agent on every turn, so it is the number to compare between servers that do the same job: ranked across the index.
