About ThreatLocker MCP

ThreatLocker MCP is an unofficial MCP server and CLI for MSP operators administering ThreatLocker. It pairs Portal API operations, including writes, with a cross-tenant local SQLite mirror for offline queries and audit retention.

Key features

  1. 01ThreatLocker Portal API operations
  2. 02Write operations for approvals and policies
  3. 03Cross-tenant SQLite mirror and search
  4. 04Audit event capture, checks, and export
  5. 05Dry-run support for planned changes

Use cases

  1. 01Triage and batch approvals across tenants
  2. 02Save audit events before retention expiry
  3. 03Export audit records for SIEM or audits
  4. 04Find stale agents and open maintenance states

MCP support

Exposes ThreatLocker Portal operations to MCP clients through `threatlocker-mcp`. HTTP mode requires a bearer token and TLS for non-loopback addresses.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Details

From the project README

ThreatLocker + AI - for ChatGPT, Claude, GitHub Copilot, Microsoft 365 Copilot, Gemini, and any agent that speaks MCP

Unofficial. Community-built Claude Code Skill and MCP server for the ThreatLocker API. Not affiliated with, endorsed by, or sponsored by ThreatLocker, Inc..

ThreatLocker - MCP server and Claude Code Skill

Full skill page - install, outcomes, safety model.

Every ThreatLocker Portal API feature, plus the write operations the read-only tools lack and a cross-tenant offline store no other ThreatLocker tool has. Works with the AI you already use - ChatGPT (Plus/Pro+, through a hosted HTTPS endpoint; see mcp-install.md), Claude Desktop, Codex, Claude Code, Claude Cowork, and GitHub Copilot - plus Microsoft 365 Copilot / Copilot Studio and Google Gemini via the remote path. Free, open source, runs on your laptop. Built for MSP owners. No code required.

Works with your agent

The six agents MSP owners actually use (self-serve, works today):

Your AI agentHow to install the ThreatLocker skill
Claude DesktopRun installer, then Settings > Extensions to register threatlocker-mcp (no JSON editing).
ChatGPT (paid plans)Run installer, host threatlocker-mcp over HTTPS with a bearer token, register it as a Developer Mode connector. See mcp-install.md.
Codex CLIPaste the install prompt below.
Claude CodePaste the install prompt below.
Claude CoworkPaste the install prompt below.
GitHub Copilot (VS Code)Run installer, add threatlocker-mcp to mcp.json under the servers key, then pick Agent mode.

ChatGPT needs a remote HTTPS server, which means this connector's HTTP mode: it refuses to start until THREATLOCKER_MCP_HTTP_TOKEN is set, every request must send that token as a bearer header, and any address other than loopback also needs --tls-cert and --tls-key. See mcp-install.md.

Also for the Microsoft and Google stacks

Big install base, but an honest heads-up: these are the remote / enterprise path, not the local binary you just installed.

AgentWhat it takes
Microsoft 365 Copilot / Copilot StudioHost threatlocker-mcp over HTTPS with a bearer token (the same HTTP mode as ChatGPT), then add it in Copilot Studio as a Model Context Protocol tool. Needs a Copilot Studio license and a tenant admin. See mcp-install.md.
Google GeminiGemini CLI is local - same as Claude Code. The Gemini app is remote and needs the same hosted HTTPS endpoint as ChatGPT. See mcp-install.md.

Skill-native agents (also covered): Hermes and OpenClaw read this skill's SKILL.md directly and speak MCP - see their install sections below. Also works with Cursor, Windsurf, Cline, Continue.dev, and Zed via MCP. Full per-tool wire-up: docs/which-agent.md.

Run more than one agent? Install across all 51+ supported agents in one command: npx skills add Servosity/msp-skills@latest (requires Node.js, then run the per-skill installer for the CLI/MCP binaries). See docs/which-agent.md.

Install in 60 seconds

Fastest for Claude Desktop - one-click .mcpb

Claude Desktop bundle: the .mcpb launches on macOS (Intel and Apple Silicon), Windows x64 and Linux x64. Every tool shells out to the companion threatlocker-cli. Releases cut from 2026-09-18 on ship that CLI inside the bundle; older bundles contain only the MCP server, so if yours lacks the companion, run the Path A or Path B installer below first (or set THREATLOCKER_CLI_PATH to an existing binary). Details: #331.

Download ThreatLocker MCP (.mcpb) - then open Claude Desktop > Settings > Extensions and select the file. One click, no JSON, no shell. (Browse every ThreatLocker release on the releases page.)

Prefer the Claude Code plugin? Add the marketplace once, then install - works immediately, no directory listing required:

/plugin marketplace add Servosity/msp-skills
/plugin install threatlocker@msp-skills
Path A - paste one prompt into your AI agent (recommended)

Copy this into Claude Code, Codex CLI, or Claude Cowork:

Install the ThreatLocker Skill and MCP server from Servosity/msp-skills in this agent workspace. If this workspace uses a POSIX shell (macOS, Linux, WSL, or Bash), run bash <(curl -fsSL https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/threatlocker/install.sh). If it uses Windows PowerShell, run iwr -useb https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/threatlocker/install.ps1 | iex. Then authenticate per the README and run threatlocker-cli --help to explore.

The same prompt works in any agent that can run shell.

Path B - run the installer yourself

Windows (PowerShell):

iwr -useb https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/threatlocker/install.ps1 | iex

macOS / Linux:

bash <(curl -fsSL https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/threatlocker/install.sh)

The installer drops both threatlocker-cli (the CLI) and threatlocker-mcp (the MCP server) into your user bin path. Claude Code, Codex, and Cowork discover the Skill via SKILL.md in this directory.

Verify:

threatlocker-cli --version
Upgrade to the latest version

The installer always fetches the current release - re-run it to upgrade:

macOS / Linux:

bash <(curl -fsSL https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/threatlocker/install.sh)

Windows (PowerShell):

iwr -useb https://raw.githubusercontent.com/Servosity/msp-skills/main/skills/threatlocker/install.ps1 | iex

Claude Desktop .mcpb users: download the latest .mcpb (top of this section) and re-select it in Settings > Extensions. Claude Code plugin users: /plugin update threatlocker@msp-skills.

Add to Claude Desktop, GitHub Copilot, Gemini CLI, Microsoft 365 Copilot, or another MCP client

After the installer runs, see mcp-install.md and docs/which-agent.md for the per-agent wire-up - one section per agent, including the GitHub Copilot servers key and the remote Microsoft 365 Copilot / Copilot Studio path. Claude Desktop's Settings > Extensions panel is the simplest path; the MCP config block (for users who prefer editing JSON) is documented in mcp-install.md.

Install for Hermes

From the Hermes CLI:

hermes skills install servosity/msp-skills/skills/threatlocker --force

Inside a Hermes chat session:

/skills install servosity/msp-skills/skills/threatlocker --force

Hermes speaks MCP natively, so it can also use the threatlocker-mcp server directly - same install path, same env vars.

Install for OpenClaw

Tell your OpenClaw agent (copy this):

Install the threatlocker skill from https://github.com/servosity/msp-skills/tree/main/skills/threatlocker. The skill defines how its required CLI (threatlocker-cli) can be installed via the openclaw: frontmatter block.

OpenClaw isn't generally available yet; the frontmatter wiring is pre-shipped and will activate the moment OpenClaw launches.

Authenticate

Set the credentials the CLI needs (from your ThreatLocker portal):

THREATLOCKER_API_KEY=<value> threatlocker-cli doctor

doctor confirms the credentials work before you run anything that touches data. It exits 0 even when the credential is rejected, so scripts should add --fail-on error.

What this skill does

Question your MSP keeps askingCommand
What application approvals are pending across all my clients right now?threatlocker-cli approvals triage --all-tenants
Approve this file hash everywhere it's pending, plan first?threatlocker-cli approvals approve-batch --hash <sha256> --all-tenants --dry-run
Which clients are about to lose audit evidence to the 31-day retention cliff?threatlocker-cli audit retention-check
Save every client's blocked-file (deny) audit events locally before they age off?threatlocker-cli audit pull --since 30d
Export that saved audit log for a SIEM or an auditor?threatlocker-cli audit export --all-tenants --since 30d
What changed across all tenants this week, protection off, policy edits, maintenance?threatlocker-cli audit drift --since 7d --all-tenants
Which ThreatLocker agents are offline or stale across every client?threatlocker-cli devices health --all-tenants
Which tenants and endpoints asked to run this file, and which applications already trust it?threatlocker-cli applications hunt --hash <sha256>
Which endpoints were left in maintenance mode?threatlocker-cli maintenance open --older-than 24h
Which tenant needs a look first?threatlocker-cli organizations posture

The audit rows read what audit pull saved, and the other rows read what sync saved: run threatlocker-cli sync and threatlocker-cli audit pull --since 30d first, and keep audit pull on a schedule shorter than 31 days.

Full command reference: guide.md. For the AI-agent operating contract (--agent, --dry-run, when to confirm before mutating), see AGENTS.md.

What makes this different

Most ThreatLocker integrations and MCP servers proxy each question into a live API call. That's fine for one record. It dies at scale, because the Portal API is scoped one tenant at a time, so asking "show me every pending approval across all 40 clients, deduped by file hash" or "which clients are about to lose audit evidence this month" turns into a header-swap-and-re-query dance the AI burns context on, tenant by tenant.

This skill syncs ThreatLocker into a local SQLite mirror with full-text search. Aggregate questions become one local SQL join: instant, offline, and the AI sees the answer, not the raw data. Compound commands like approvals triage, applications hunt, and devices health join approval requests, applications, computers, and audit events across every tenant at once - work a stateless API wrapper can't do.

The pain this closes

ThreatLocker is default-deny, so every new or updated application becomes an approval request an admin has to clear. ThreatLocker's own MSP guide admits the volume: "While you are onboarding your first few clients, your devices are learning and can be quite noisy" (Allowlisting for MSPs). Across a book of tenants the queue never goes quiet, and the Portal makes you clear it one tenant at a time. Then there's evidence: ThreatLocker's Help Center is explicit that "by default, the Unified Audit retains data for 31 days. After 31 days, the information is permanently deleted and cannot be recovered" (Log Retention) - shorter than most compliance and cyber-insurance asks.

This skill closes both:

  • approvals triage --all-tenants - one ranked queue of every pending approval across all tenants, deduped by file hash.
  • approvals approve-batch --hash <sha256> --all-tenants --dry-run - permit a known-good file everywhere it's pending, plan first; the live run needs --yes.
  • audit pull --since 30d + audit retention-check - save every tenant's deny events locally before evidence ages off (--action permit adds permitted events), and flag tenants near the 31-day cliff; audit export hands the saved log to a SIEM or an auditor.
  • devices health --all-tenants - surface dark and stale agents across the whole book without a tenant-by-tenant sweep.

See pain-point.md for the longer narrative.

Frequently asked questions

Does this work with ChatGPT?

Yes, on Plus, Pro, Team, Business, Enterprise, and Education plans (Free does not yet expose Developer Mode). ChatGPT connects only to remote MCP servers over HTTPS, so you host threatlocker-mcp in HTTP mode: it refuses to start until THREATLOCKER_MCP_HTTP_TOKEN is set, every request must send that token as a bearer header, and any address other than loopback also needs --tls-cert and --tls-key. The connector works only if its authentication settings can send that bearer token, so check yours first. Step-by-step in mcp-install.md.

Does this work with Codex, Cursor, Windsurf, Cline, Copilot, or Gemini?

Yes - all of them speak MCP. Cross-tool install commands are in the matrix above and the deep-dive in docs/which-agent.md.

Do I need to know how to code?

No. The recommended install is to paste one sentence into Claude Code or Codex - your agent reads SKILL.md and does the install. The fallback is a one-line installer per OS (bash or PowerShell). Neither path requires writing code. You'll enter your ThreatLocker credentials once.

Is my ThreatLocker data safe?

Your data stays on your machine. The CLI and MCP server are local binaries. The SQLite mirror sits in a directory under your user account. The AI agent only sees what the CLI returns - typically a query result, not raw bulk data. Credentials are read from your environment or your agent's config; never bundled into this repo or transmitted anywhere by MSP Skills.

Will this hit my ThreatLocker API rate limits?

The local mirror exists so reads stop hitting the API. After the first sync, the cross-tenant views (approvals triage, audit drift, devices health, applications hunt) run against local SQLite with zero API calls. Live calls respect a --rate-limit throttle, and sync is incremental, fetching only what changed since the last checkpoint.

How does it handle ThreatLocker's 31-day audit retention?

ThreatLocker's Unified Audit log keeps about 31 days by default. audit pull saves each tenant's deny events (or, with --action permit, permitted ones) to the local store so the evidence outlives that window, audit export writes it out as JSONL or CSV, and audit retention-check reports, per tenant, how close your archive is to the cliff and how stale your last sync is, so nothing ages off unnoticed.

Do I need to be a ThreatLocker MSP or have child tenants?

You need API access in your own ThreatLocker Portal. The cross-tenant features assume a managed (parent) organization with child tenants, the MSP setup, but a single organization works too, you just get the one-tenant view. The credential you mint is the real permission boundary.

Does it replace the ThreatLocker Portal?

No. The Portal stays best for authoring policies and the interactive approve/deny workflow. This skill adds cross-tenant queries and scriptable writes to your AI agent so you stop logging into each tenant to answer book-wide questions.

What does it cost?

Free. Apache-2.0 licensed. You pay only for whichever AI agent you use (Claude, ChatGPT, Codex, etc.), and that's billed by your AI provider, not by us.

The strongest control is the scope you grant the ThreatLocker credentials - the CLI can only do what the credentials are permitted to do. Full details, including how to lock it down, are in governance.md.
