trmm-action-mcp

trmm-action-mcp

A gated, allow-listed action server for Tactical RMM. Unlike the read-only trmm-mcp server, this one can act on endpoints — but only by running a vetted, read-only audit from a fixed catalog. There is deliberately no tool to run arbitrary code and no tool to delete, edit, reboot, or uninstall anything.

Built for a small group of senior engineers (e.g. the approved engineers) to run audits like "list Domain Admins on EF-DC01" from Claude.

Why it's safe — six independent guardrails

  1. Identity — reachable only by the named senior engineers.

  2. Network — nginx allows only Anthropic's connector egress IPs (+ your IPs).

  3. Bearer — shared secret between the edge and this backend.

  4. Restricted tools — only list_agents, list_audits, run_audit.

  5. Allow-listed auditsrun_audit runs only vetted read-only scripts in catalog.py; no arbitrary-code path exists.

  6. Scoped TRMM key — the claude-actions role can Send-Command + read, nothing else. Every run is TRMM-audit-logged.

"Can't delete stuff" is a guarantee here (allow-listed catalog + no delete tools + scoped key), not a hope — see the note in catalog.py.

Tools

Tool

Kind

What it does

trmm_list_agents

read

Find the agent to target (filter by client/site/type/platform/status/hostname).

trmm_list_audits

read

The catalog of runnable audits (the only scripts run_audit will execute).

trmm_run_audit

action

Run ONE vetted audit on ONE agent; returns its output. readOnlyHint:false.

Audit catalog (v1)

privileged_groups (DC), local_admins, local_users, disk_space, os_info, installed_software, services_not_running, pending_reboot, hotfixes, logged_on_users, bitlocker, network_config. All read-only. Add more by vetting a new entry in catalog.py.

Configuration

Variable

Required

Description

TRMM_API_URL

TRMM API base URL (api. subdomain).

TRMM_ACTION_API_KEY

The scoped claude-actions key (Send-Command + read only).

TRMM_MCP_TRANSPORT

stdio (default) or http.

TRMM_MCP_AUTH_TOKEN

http only

Shared bearer between edge and backend.

TRMM_MCP_HOST / PORT / PATH

Default 0.0.0.0 / 8090 / /mcp (in Docker).

TRMM_TIMEOUT / TRMM_VERIFY_SSL / TRMM_MAX_RETRIES

Tuning.

Run

python -m venv .venv && .venv\Scripts\activate   # or source .venv/bin/activate
pip install -r requirements.txt
# stdio (local dev): set TRMM_API_URL + TRMM_ACTION_API_KEY, then:
python -m trmm_action_mcp

Deploy (gated, remote)

See docs/DEPLOY.md (Docker + nginx Anthropic-IP allowlist + identity options) and docs/TRMM_ROLE.md (the scoped key). The senior-engineer path that works today is Claude Code/Desktop + bearer behind the nginx allowlist; per-user Entra SSO for claude.ai web/mobile is best done via Cloudflare Access (see the read-only project) — DEPLOY.md explains the trade-offs.

Relationship to trmm-mcp

Separate project, separate key, separate deploy on purpose: the read-only server stays incapable of acting, and this one stays incapable of anything but vetted audits.
