✓ Watched since 2026-06-03 — behavioral baseline locked. We re-check this server's tool surface on a schedule; if it adds, removes, or silently rewrites a tool (rug-pull), we record it.

What it offers — 6 tools · Docs & Knowledge

list_queues

List all queues owned by your agent key. Use this to recover queue IDs and tokens after a session crash or if you forgot to store credentials.

create_queue

Provision a new message queue. Returns queue_id, push_token, and poll_token. The push_token allows pushing messages; the poll_token allows polling and

push_message

Push a message to a queue. Requires the push_token for that queue. Default TTL is 24 hours; set ttl_seconds for a shorter or longer expiry (max 7 days

poll_messages

Retrieve pending messages from your queue. Returns all messages not yet deleted, ordered oldest-first. Messages are NOT auto-deleted on poll — call de

delete_message

Acknowledge and delete a message after processing. Required to prevent redelivery.

queue_info

Get stats for a queue: current depth, messages sent today, and rate limit status.

Observed behavior

No proxied traffic observed for this host yet. Connect it at /connect and its grade gains a measured Reliability score + per-tool behavioral evidence — the half a static scan can't produce.

Findings

No blocking issues found in the static + spec checks.

Grade another server

We re-grade crabbitmq.com on a schedule and alert your Slack/webhook the moment its tools change or its grade drops — rug-pull insurance for the connection.

Agents: check this before connecting

Add the wmcp.sh trust oracle as an MCP server and call grade_mcp_server / check_mcp_drift in your agent's pre-connection gate:

How this grade is computed. An open, independent rubric — Spec conformance (20%), Security mapped to the OWASP MCP Top 10 (30%), Reliability (20%), Tool hygiene (15%), Transparency (15%) — run by connecting to the server and inspecting its real MCP surface. The grade is free and identical whether or not the operator pays. v1 uses static + spec signals from a single connection; continuous uptime, real latency, and annotation-truthing (declared readOnly vs observed behavior) layer on via the wmcp.sh proxy.
