Publisher claims: "Meridian — Local-first AI compliance scanner. DPDPA 2023 · RBI FREE-AI · SEBI AI/ML · EU AI Act. Works with any LLM provider. AST-level code analysis across Python, TypeScript, Go, Java." 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: 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
MERIDIAN_API_KEYS_DB_PATHConfiguration, not credentials: MERIDIAN_ALLOW_LOCAL_PATH_SCAN, MERIDIAN_ALLOWED_GIT_HOSTS, MERIDIAN_APP_URL, MERIDIAN_AUDIT_LOG_DB_PATH, MERIDIAN_BACKEND_URL, MERIDIAN_BOOTSTRAP_ADMIN_KEY, MERIDIAN_CLONE_TIMEOUT_SECONDS, MERIDIAN_CRITIC_MODEL, MERIDIAN_DB_PATH, MERIDIAN_EVALUATOR_MODEL, MERIDIAN_HOME, MERIDIAN_INTERPRETER_MODEL, MERIDIAN_LEDGER_DIR, MERIDIAN_LOG_LEVEL, MERIDIAN_MAX_CLONE_MB, MERIDIAN_MAX_CONCURRENT, MERIDIAN_MAX_REQUEST_BODY_BYTES, MERIDIAN_OFFLINE, MERIDIAN_REMOTE_ASSESSMENT_TIMEOUT_SECONDS, MERIDIAN_REMOTE_SESSION_TTL_SECONDS, MERIDIAN_REQUEST_TIMEOUT_SECONDS, MERIDIAN_RPM_LIMIT, MERIDIAN_TPM_LIMIT
Where it talks to
no vendor host named in the codeAlso framer.website, railway.app — 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
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names framer.website, railway.app as well as its own vendor. The guard injects MERIDIAN_API_KEYS_DB_PATH only into requests to the host you bind (and its subdomains) and refuses the rest.

$vet-skills run --net declared -- uvx meridian-mcp

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 2026-11-11 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.
