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
MCP_TELEMETRY_API_KEY or --jwt-tokenConfiguration, not credentials: AWS_DEFAULT_REGION, AWS_REGION, FASTMCP_ADDR, FASTMCP_HOST, FASTMCP_PORT, FASTMCP_TRANSPORT, MCP_SKIP_BANNER, MCP_TELEMETRY_BATCH_SIZE, MCP_TELEMETRY_ENDPOINT, MCP_TELEMETRY_FLUSH_INTERVAL, MCP_TELEMETRY_LEVEL, MCP_TELEMETRY_LOCAL_ONLY, MCP_TELEMETRY_PRIVACY_LEVEL, MCP_TELEMETRY_SESSION_TIMEOUT, QUILT_ALLOW_TEST_JWT, QUILT_CATALOG_URL, QUILT_DEPLOYMENT, QUILT_DISABLE_USAGE_METRICS, QUILT_MCP_RESOURCE_ACCESS_LOGGING, QUILT_MCP_RESOURCE_CACHE_ENABLED, QUILT_MCP_RESOURCE_CACHE_TTL, QUILT_MCP_RESOURCES_ENABLED, QUILT_MULTIUSER_MODE, QUILT_NAVIGATOR_URL, QUILT_REGISTRY_URL, QUILT_SERVICE_TIMEOUT, QUILT_TEST_BUCKET, QUILT_TEST_ENTRY, QUILT_TEST_PACKAGE, QUILT_WORKFLOW_DIR, TEST_QUILT_CATALOG_URL, VAR, VAR_NAME
Where it talks to
quiltdata.com, quilttest.com, quiltdata.cloud, quilt.bio (its own)Also astral.sh — 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 astral.sh as well as its own vendor. The guard injects MCP_TELEMETRY_API_KEY only into requests to quiltdata.com (and its subdomains) and refuses the rest.

$vet-skills run --secrets MCP_TELEMETRY_API_KEY=quiltdata.com -- uvx quilt-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 2026-11-15 and scored it 78/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Pipe-to-shell pattern; Access to sensitive file paths; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
