Queue AIops

Governed AI-ops for redis + rabbitmq. queue-aiops is for the team running their own cache and message broker — a redis that "suddenly eats memory", a rabbitmq whose queues quietly grow until publishers block — without an enterprise observability suite. It gives an AI agent (or a human at the CLI) a governed toolset over both: transparent root-cause analyses for memory pressure, latency, queue backlog, and connection churn, plus the handful of writes an operator actually needs (config set, client kill, purge/delete queue, policies) — every call audited, budgeted, risk-tiered, and undo-recorded by the built-in governance harness.

Verification: behaviour is covered by a mock-based test suite; not yet validated against live brokers. Both redis and rabbitmq are free/self-hostable (one lab container or package install each), so a lab check is easy — queue-aiops doctor is the fastest live probe, and docs/VERIFICATION.md is the checklist.

Quick start

uv tool install queue-aiops

queue-aiops init      # wizard: pick platform (redis/rabbitmq), host/port, encrypted secret
queue-aiops doctor    # config + secret + connectivity check (PING / /api/overview)
queue-aiops overview  # one-shot health summary for the default target

Then the interesting parts:

queue-aiops analyze memory     # redis memory-pressure RCA (maxmemory, eviction, frag, big keys)
queue-aiops analyze latency    # redis latency RCA (slowlog digest, fork/AOF stalls)
queue-aiops analyze backlog    # rabbitmq queue-backlog RCA (consumers, unacked, watermarks)
queue-aiops analyze churn      # connection churn, both platforms
queue-aiops redis bigkeys      # SCAN-budgeted big-key sample (never KEYS *)
queue-aiops rabbitmq queues    # deepest backlog first

What this tool does, and does not, decide

It delivers broker operations — reads and writes — accurately and efficiently, and records every one of them. It does not decide whether a write is allowed to happen. That is the agent's judgement, or the permission of the account you connect it with: give the Redis connection an ACL user restricted to read commands, or the RabbitMQ management user only the monitoring tag, and the writes fail at the broker — the place that actually owns the permission.

So there is no read-only switch, no policy file, no approval gate to configure. The one thing the tool guarantees is that nothing is silent: every call, over MCP and over the CLI alike, lands an audit row in ~/.queue-aiops/audit.db, and reversible writes still capture their before-state and record an inverse.

Each tool declares a risk_level, kept in agreement with its [READ]/[WRITE] documentation tag by a test, and carried into the audit row as a descriptive tier — so a reviewer can see at a glance that a row was a high-risk delete. It is a label, not a gate.

Running a smaller / local model? See agent-guardrails.md — it lists the guardrails this tool now enforces for you (so you don't spend prompt budget restating them) and gives a ready-made system prompt for what's left.

Support scope

Platform	Protocol	Coverage
redis (5.x–7.x wire protocol via redis Python client)	RESP, password optional, TLS optional	INFO (server/memory/clients/stats/persistence/keyspace), SLOWLOG, CLIENT LIST/KILL, CONFIG GET/SET, MEMORY STATS/USAGE, SCAN-budgeted big-key sampling, DBSIZE, PING
rabbitmq (management plugin HTTP API)	HTTP(S), Basic auth	/api/overview, /api/queues (+ per-vhost, detail, purge, declare, delete), /api/connections, /api/channels, /api/consumers, /api/policies (get/set/delete), /api/nodes

28 MCP tools — 20 reads (incl. 4 flagship RCAs) + 8 governed writes.

Group	Tools	R/W
Overview	queue_overview	read
redis reads	redis_server_info, redis_memory_stats, redis_clients, redis_slowlog, redis_config_get, redis_keyspace, redis_big_keys	read
rabbitmq reads	rabbitmq_overview, list_queues, queue_detail, list_connections, list_channels, list_policies, node_health	read
Flagship RCAs	redis_memory_pressure_rca, redis_latency_rca, rabbitmq_queue_backlog_rca, connection_churn_analysis	read
Writes (medium)	redis_config_set, redis_kill_client, declare_queue, set_policy, delete_policy	write
Writes (high)	purge_queue, delete_queue	write
Undo	undo_list, undo_apply	read / write

The four RCAs are transparent heuristics that report their numbers — thresholds are named constants, every finding carries its evidence, never a black-box verdict. Big-key sampling walks at most 10,000 keys with SCAN and sizes at most 200 with MEMORY USAGE — never KEYS * — and reports its coverage.

Governance

Every MCP tool — and every CLI write, which routes through the same governed functions — runs through the bundled @governed_tool harness (queue_aiops.governance — no external dependency). It records; it does not authorize whether a write may happen (see above):

• Audit — every call lands in ~/.queue-aiops/audit.db (relocatable via QUEUE_AIOPS_HOME), secret-redacted. The CLI writes the same row the MCP path does — there is no unaudited entry point.
• Budget / runaway guard — a safety backstop, not an authorization gate: call/time ceilings (QUEUE_MAX_TOOL_CALLS, QUEUE_MAX_TOOL_SECONDS) + a runaway-loop breaker stop a stuck agent from burning unbounded calls/time.
• Risk tier — a descriptive label on the audit row derived from risk_level; it gates nothing. QUEUE_AUDIT_APPROVED_BY / QUEUE_AUDIT_RATIONALE are optional annotations recorded on the row (who/why), never required and never blocking.
• Undo — reversible writes capture the real before-state first: redis_config_set records the prior value from CONFIG GET; set_policy/delete_policy record the prior policy; delete_queue records the queue's definition and its undo re-declares it (the messages are not restored — the descriptor says so). Irreversible writes (purge_queue, redis_kill_client) record priorState only.
• Dry-run + double-confirm — every write takes dry_run=True (MCP) / --dry-run (CLI); CLI writes double-confirm and execute through the same governed twins, so they land in the audit log too. purge_queue and delete_queue are risk=high with dry-run + double confirmation at the CLI.
• Credentials live encrypted in ~/.queue-aiops/secrets.enc (Fernet + scrypt master password; QUEUE_AIOPS_MASTER_PASSWORD for non-interactive use). Redis passwords are optional — an auth-less lab instance is a supported target.

MCP configuration

{
  "mcpServers": {
    "queue-aiops": {
      "command": "uvx",
      "args": ["--from", "queue-aiops", "queue-aiops-mcp"],
      "env": {
        "QUEUE_AIOPS_MASTER_PASSWORD": "your-master-password"
      }
    }
  }
}

env-block caveat: MCP clients launch the server with a minimal environment — your shell profile is not sourced. Anything the server needs (QUEUE_AIOPS_MASTER_PASSWORD, a relocated QUEUE_AIOPS_HOME, and any optional QUEUE_AUDIT_APPROVED_BY/QUEUE_AUDIT_RATIONALE audit annotations) must be set in the env block above, not just in your terminal.

Or, with the package installed: queue-aiops mcp.

Verification status

Live-verified against Redis 7.4.9 and RabbitMQ 3.13.7 (2026-07-19/20). Connectivity, every Redis read (cross-checked against redis-cli ground truth), all four analyses, and the full governance loop (real redis_config_set → audit row → undo restoring the prior value) were exercised against a real server. That run found and fixed a real defect: integer quantities — key counts, client counts, byte totals — were rendered as floats (202.0 keys), which equality assertions cannot catch.

The RabbitMQ group is now verified end-to-end too — reads cross-checked against rabbitmqadmin, and set_policy → undo_apply closing on the live broker. Redis cluster/sentinel topologies and AUTH/TLS connections remain unverified.

docs/VERIFICATION.md records exactly what was checked and what is still open. queue-aiops doctor is the fastest live check.
