// key findings
⚠️
Known vulnerabilities in dependencies: 3 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
🔐
You'll be asked for 1 credential: RABBITMQ_PASSWORD
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// tools this server exposes21 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

list_connections

List active RabbitMQ connections with client info, state, and channel count.

list_consumers

List active consumers with their queue assignments, prefetch, and connection info.

list_exchanges

List exchanges with type and binding info. Filter by vhost, name pattern, or type.

get_exchange

Get exchange details and its bindings (both source and destination).

list_bindings

List bindings for a specific queue or exchange.

list_log_files

List RabbitMQ log files on configured nodes. Node names match the `node` field from get_queue, get_overview, and list_connections tools — use this to cross-reference which node a queue or connection is on and then check that node's logs.

read_log

Read RabbitMQ log file content from a node. Returns the last N lines (tail mode) by default. Node names match the `node` field from get_queue, get_overview, and list_connections tools.

search_logs

Search RabbitMQ log files for a text pattern or regex. Searches the current log by default; optionally includes rotated logs. Node names match the `node` field from get_queue, get_overview, and list_connections tools.

list_error_queues

Find all MassTransit _error queues with message counts. Helps identify services with unprocessed failures.

list_skipped_queues

Find all MassTransit _skipped queues with message counts. Skipped messages indicate routing or serialization issues.

peek_errors

Browse error queue messages with parsed MassTransit fault details: exception type, message, stack trace, original payload, and source host.

get_queue_health

Quick health check: find queues with no consumers, growing depth, or high error counts. Identifies potential issues.

republish_from_error

Fetch messages from a MassTransit _error queue and republish them to their original exchange for reprocessing. Two-step: first call shows message details, second call with confirm=true executes the republish.

peek_messages

Browse messages in a queue without consuming them (non-destructive). Parses MassTransit envelopes when detected.

publish_message

Publish a message to an exchange with a routing key. The message is sent with MassTransit-compatible content type.

move_messages

Move messages from one queue to another by consuming from source and publishing to destination exchange. DESTRUCTIVE — removes messages from source queue.

get_overview

Get RabbitMQ cluster overview: queue totals, connection counts, message rates, and version info

list_queues

List queues with message depth, consumer count, and rates. Filter by vhost and name pattern.

get_queue

Get detailed stats for a specific queue: depth, rates, consumers, memory, policy, arguments.

purge_queue

Purge all messages from a queue. DESTRUCTIVE — messages cannot be recovered.

delete_queue

Delete a queue entirely. DESTRUCTIVE — queue and all messages will be lost.

Tool annotations

4/21 tools have annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

21/21 tools missing one or more hints — list_connections (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_consumers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_exchanges (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +18 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool handlers catch errors

Only 4/21 tool handlers wrap calls in try/catch (19%)

Wrap each tool handler body in try/catch and return a structured error response.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
