tracecat-mcp-community

A full-stack Model Context Protocol (MCP) server for the Tracecat SOAR platform — 94 tools across 16 domains.

---

What is this?

An MCP server that gives AI assistants (Claude Code, Claude Desktop, etc.) full control over a Tracecat instance through natural language. Manage workflows, actions, cases, secrets, tables, schedules, graphs, and more — without leaving your editor.

• 94 tools covering the full Tracecat API surface, including write operations not exposed by the official MCP
• Stdio transport — no OIDC/SSO setup required, works against any self-hosted Tracecat
• Lazy authentication — MCP transport starts instantly, login happens on first tool call
• Auto workspace detection — no manual workspace ID needed
• Session cookie auth — handles Tracecat's cookie-based auth transparently

---

Community MCP vs Official MCP

Tracecat ships an official MCP server (HTTP transport, OIDC auth, bundled with the platform). This community MCP is a standalone alternative you can use instead — pick the one that fits your setup.

	Community MCP (this project)	Official MCP
Transport	stdio (local)	HTTP (remote)
Auth	Session cookie (username/password)	OIDC / SSO
Setup	npx tracecat-mcp-community + .env	Requires OIDC configured on the Tracecat instance
Tool coverage	94 tools — full CRUD + graph ops + autofix + variables/integrations	~90 tools — read + basic CRUD, plus agents/skills (EE-oriented)
Exclusive capabilities	Graph editing (add_edges, move_nodes, autofix_workflow), Schedules CRUD, Secrets write, Cases CRUD + tasks + fields, Actions CRUD, Variables CRUD, Integrations management, Templates, Webhook key rotation	Agent presets/skills/sessions (Enterprise Edition), official support, platform-integrated
Best for	Local dev, self-hosted without SSO, workflow authoring/editing at scale	Teams already running Tracecat Cloud or self-hosted with OIDC

You don't need both. This community MCP is designed to cover the full surface on its own.

Quick Start

Option A: npx (fastest)

# Install globally
npm install -g tracecat-mcp-community

Create a .env file wherever you run from (or in the package directory):

TRACECAT_API_URL=http://localhost/api
TRACECAT_USERNAME=your-email@example.com
TRACECAT_PASSWORD=your-password-here
TRACECAT_WORKSPACE_ID=              # Optional — auto-detected if omitted

Add to your .mcp.json:

{
  "mcpServers": {
    "tracecat": {
      "command": "npx",
      "args": ["-y", "tracecat-mcp-community"]
    }
  }
}

Option B: From source

git clone https://github.com/adrojis/tracecat-mcp-community.git
cd tracecat-mcp-community
npm install
cp .env.example .env    # Edit with your credentials
npm run build

Add to your .mcp.json:

{
  "mcpServers": {
    "tracecat": {
      "command": "node",
      "args": ["/absolute/path/to/tracecat-mcp-community/dist/index.js"]
    }
  }
}

Option C: Docker

git clone https://github.com/adrojis/tracecat-mcp-community.git
cd tracecat-mcp-community
docker build -t tracecat-mcp-community .

{
  "mcpServers": {
    "tracecat": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "--env-file", "/path/to/.env", "tracecat-mcp-community"]
    }
  }
}

Security: .env is gitignored and never committed. Never hardcode credentials in source files. See SECURITY.md.

Then restart Claude Code and verify with /mcp — you should see the tracecat server with 94 tools.

Configuration

Variable	Required	Default	Description
TRACECAT_API_URL	No	http://localhost/api	Tracecat API base URL
TRACECAT_USERNAME	Yes	—	Login email
TRACECAT_PASSWORD	Yes	—	Login password
TRACECAT_WORKSPACE_ID	No	Auto-detected	Workspace ID (uses first workspace if omitted)

Credentials are loaded from .env via dotenv. The .env file must be in the project root (next to package.json).

Key Design Decisions

Decision	Rationale
Lazy initialization	MCP transport starts immediately; login happens on first tool call. Avoids blocking Claude Code startup.
Session cookies	Tracecat currently uses fastapiusersauth cookies, not API keys. The client handles login and cookie extraction automatically. See note below on upcoming API token support.
YAML string inputs	Action inputs are sent as YAML strings per the Tracecat API contract, not JSON objects.
POST for updates	Actions, secrets, and schedules use POST for updates instead of the conventional PATCH.
Auto workspace injection	workspace_id is auto-detected and injected as a query parameter on every request.
Optimistic locking	Graph operations read base_version before patching to prevent concurrent edit conflicts.

---

Authentication Roadmap

This server currently authenticates via username/password (session cookies). The Tracecat team is actively working on API token authentication, which will provide a simpler and more secure connection method — no more password in .env.

We will add API token support as soon as it becomes available upstream. The username/password method will remain supported for backward compatibility.

---

API Quirks

These behaviors differ from typical REST conventions and are handled transparently by the server:

Quirk	Details
workspace_id as query param	Must be ?workspace_id=..., not a header
POST for updates	/actions/{id}, /secrets/{id}, /schedules/{id} use POST
Actions list endpoint	GET /actions?workflow_id=... (not nested under /workflows)
Action inputs format	YAML string, not JSON object
Workflow list pagination	Returns { items: [...], next_cursor }, not a plain array

---

Development

# Watch mode (auto-reload)
npm run dev

# Build TypeScript
npm run build

# Run directly
node dist/index.js

Testing

npm run build
npm test

Tests use Node.js built-in test runner (no extra dependencies). See CONTRIBUTING.md for guidelines.

MCP Inspector

The MCP Inspector is a visual debugging tool that lets you browse and test all 94 tools interactively in your browser — useful for verifying your setup, exploring tool schemas, and testing API calls without Claude.

From the project root:

npx @modelcontextprotocol/inspector node dist/index.js

This starts a local web UI (default: http://localhost:6274). Click the Tools tab to see all available tools, inspect their input schemas, and execute them against your Tracecat instance.

---

Roadmap

This project is under active development. Tracecat's API surface evolves fast, and we intend to keep up — expect new tools, refinements, and breaking-change adaptations as the platform matures.

Planned areas of improvement:

• More tools — covering new Tracecat API endpoints as they ship
• Better error handling — structured error responses with actionable hints
• OAuth/OIDC support — for Tracecat instances using SSO instead of basic auth
• Test suite — automated integration tests against a live Tracecat instance

Contributions, issues, and feature requests are welcome.

Related Projects

• Tracecat official MCP — HTTP/OIDC MCP bundled with the platform (alternative to this one)
• tracecat-skills — Claude Code skills for Tracecat workflow building
• Tracecat — The open-source SOAR platform
• MCP SDK — Model Context Protocol TypeScript SDK

Note: This project was previously named tracecat-mcp. It was renamed to tracecat-mcp-community in April 2026 to distinguish it from Tracecat's official MCP server (HTTP + OIDC), which shipped shortly after.
