FortiManager MCP Server
A Model Context Protocol (MCP) server for FortiManager JSON-RPC API. This server enables AI assistants like Claude to interact with FortiManager for centralized firewall policy management, device provisioning, and network configuration.
Note: This is an independent open-source project and is not affiliated with, endorsed by, or supported by Fortinet, Inc. FortiManager is a trademark of Fortinet, Inc.
Disclaimer: This MCP server can create, modify, and delete configurations on FortiManager. Misuse or misconfiguration can impact production networks. Use at your own risk. Always test in a non-production environment first and ensure appropriate ADOM permissions are configured.
Overview
This MCP server provides a comprehensive interface to FortiManager's capabilities, allowing AI assistants to:
- Create and manage firewall policies and policy packages
- Configure firewall objects (addresses, services, VIPs)
- Add, provision, and manage FortiGate devices
- Execute CLI scripts on managed devices
- Configure provisioning and SD-WAN templates
- Monitor tasks and installations
- Manage ADOMs and workspace locking

# Allowed Host headers for HTTP/Docker deployments (optional)
# Set to the value clients use in their connection URL — NOT the client's IP.
# The MCP SDK rejects non-localhost Host headers by default for DNS rebinding protection.
# Examples: ["mcp.example.com"], ["10.1.5.62:8000"], or wildcard ["10.1.5.62:*"]
# MCP_ALLOWED_HOSTS=["mcp.example.com"]
# Safety Guardrails (optional - strict by default)

# FMG_POLICY_SAFETY=strict # Block overly permissive policies (srcaddr=all + dstaddr=all + accept)
Tool Loading Modes
FortiManager MCP supports two tool loading modes to optimize context window usage:
| Mode | Tools Loaded | Context Usage | Best For |
|---|---|---|---|
full (default) |
All 102 tools | ~100% | Large context windows, full functionality |
dynamic |
4 discovery tools | ~10% | Smaller context windows, on-demand loading |
Full Mode (default): All 102 tools are loaded at startup. Best when you have sufficient context window and need immediate access to all FortiManager operations.
Dynamic Mode: Only lightweight discovery tools are loaded:
find_fortimanager_tool(operation)- Search for tools by keywordlist_fortimanager_categories()- List tool categoriesexecute_fortimanager_tool(name, params)- Execute any tool by namehealth_check()- Server health status
To enable dynamic mode:
FMG_TOOL_MODE=dynamic
Default ADOM
The DEFAULT_ADOM environment variable sets the default Administrative Domain (ADOM) for all FortiManager operations. When a tool is called without specifying an ADOM, this value is used.
DEFAULT_ADOM=root # default value
This is particularly useful when:
- Your FortiManager only uses a single ADOM
- Most of your work is within one specific ADOM
- You want to avoid repeatedly specifying the ADOM in each tool call
If not set, defaults to root (the global ADOM).
Generating an API Token
- Log into FortiManager web interface
- Go to System Settings > Admin > Administrators
- Edit your admin user or create a new one
- Under JSON API Access, click Regenerate or New API Key
- Copy the generated token
Running the Server
Standalone Mode
# Using the installed command
fortimanager-mcp
# Or using Python module
python -m fortimanager_mcp
Claude Desktop Integration
Add to your Claude Desktop configuration file:
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
{
"mcpServers": {
"fortimanager": {
"command": "/path/to/fortimanager-mcp/.venv/bin/fortimanager-mcp",
"env": {
"FORTIMANAGER_HOST": "your-fmg-hostname",
"FORTIMANAGER_API_TOKEN": "your-api-token",
"FORTIMANAGER_VERIFY_SSL": "true",
"LOG_LEVEL": "INFO"
}
}
}
}
Note: Use the full path to the fortimanager-mcp executable in your virtual environment.
Claude Code Integration
Add to ~/.claude/mcp_servers.json:
{
"mcpServers": {
"fortimanager": {
"command": "/path/to/fortimanager-mcp/.venv/bin/fortimanager-mcp",
"env": {
"FORTIMANAGER_HOST": "your-fmg-hostname",
"FORTIMANAGER_API_TOKEN": "your-api-token",
"FORTIMANAGER_VERIFY_SSL": "true",
"DEFAULT_ADOM": "root",
"LOG_LEVEL": "INFO"
}
}
}
}
Docker Mode
# Start the server
docker compose up -d
# View logs
docker compose logs -f
# Stop the server
docker compose down
HTTP Mode (Remote Access)
When running in HTTP mode (Docker or standalone with MCP_SERVER_MODE=http), MCP clients connect via the Streamable HTTP transport:
Claude Code (~/.claude/mcp_servers.json):
{
"mcpServers": {
"fortimanager": {
"type": "streamable-http",
"url": "https://your-mcp-host.example.com/mcp",
"headers": {
"Authorization": "Bearer your-mcp-auth-token"
}
}
}
}
Claude Desktop (claude_desktop_config.json):
{
"mcpServers": {
"fortimanager": {
"type": "streamable-http",
"url": "https://your-mcp-host.example.com/mcp",
"headers": {
"Authorization": "Bearer your-mcp-auth-token"
}
}
}
}
Production Deployment (Reverse Proxy)
For production deployments behind a TLS-terminating reverse proxy:
MCP Client → HTTPS → Reverse Proxy (Traefik/nginx) → HTTP → MCP Container → FortiManager
Key considerations:
-
MCP_ALLOWED_HOSTS — The MCP SDK validates the Host header to prevent DNS rebinding attacks. By default only
localhostand127.0.0.1are accepted. Set this to the value clients put in their connection URL (NOT the client's IP):# Reverse-proxy hostname (Traefik/nginx): MCP_ALLOWED_HOSTS=["mcp.example.com"] # Direct Docker exposure on IP+port: MCP_ALLOWED_HOSTS=["10.1.5.62:8000"] # Port wildcard (any port on the host): MCP_ALLOWED_HOSTS=["10.1.5.62:*"] -
MCP_AUTH_TOKEN — Always set a Bearer token for HTTP deployments:
MCP_AUTH_TOKEN=$(openssl rand -hex 32) -
Secrets management — Keep API tokens and auth tokens in an
env_file(.env), not inline indocker-compose.yml.
Example with Traefik:
services:
fortimanager-mcp:
image: ghcr.io/rstierli/fortimanager-mcp:latest
container_name: fortimanager-mcp
restart: unless-stopped
security_opt:

- FORTIMANAGER_HOST=your-fmg-hostname
# Keep TLS verification on; import the FortiManager CA for self-signed
# certs. FORTIMANAGER_VERIFY_SSL=false disables MITM protection.

API Reference
The server communicates with FortiManager using the JSON-RPC API over HTTPS. All requests are sent to the /jsonrpc endpoint.
Supported FortiManager Versions
- FortiManager 7.0.x
- FortiManager 7.2.x
- FortiManager 7.4.x
- FortiManager 7.6.x (primary development target)
Authentication Methods
-
API Token (Recommended)
- More secure, no session management
- Tokens can be revoked without changing passwords
- Works with FortiManager 7.0+
-
Username/Password
- Traditional session-based authentication
- Session automatically managed by the client
Troubleshooting
Enable Debug Logging
Set LOG_LEVEL=DEBUG in your environment to see detailed API requests and responses:
LOG_LEVEL=DEBUG fortimanager-mcp
Common Issues
Connection Failed
- Verify FortiManager hostname/IP is correct
- Check network connectivity and firewall rules
- Ensure HTTPS port (443) is accessible
Authentication Failed
- Verify API token or credentials are correct
- Check if the admin account has API access enabled
- Ensure the account has sufficient permissions
SSL Certificate Errors
- For self-signed FortiManager certs, import the FortiManager CA certificate
into your trust store and keep
FORTIMANAGER_VERIFY_SSL=true(see SETUP_GUIDE.md → "Trusting the FortiManager CA") - For production, use valid SSL certificates signed by a trusted CA
- Last resort only:
FORTIMANAGER_VERIFY_SSL=falsedisables TLS verification and exposes the connection to man-in-the-middle attacks — avoid in production
ADOM Locked
- Another user may have the ADOM locked
- Use
unlock_adomto release the lock (requires permissions) - Check workspace mode settings in FortiManager
MCP Transport Issues
Invalid Host header (HTTP/Docker mode)
Symptom — server logs show:
mcp.server.transport_security - WARNING - Invalid Host header: 10.x.y.z:8000
INFO: ... "POST /mcp HTTP/1.1" 421 Misdirected Request
Cause: the MCP SDK validates the Host header for DNS rebinding protection. By default only localhost and 127.0.0.1 are accepted. The header value is whatever the client puts in its connection URL — not the client's IP.
Fix: add the URL value (with port, if used) to MCP_ALLOWED_HOSTS:
# If the client connects to http://10.1.5.62:8000/mcp:
MCP_ALLOWED_HOSTS=["10.1.5.62:8000"]
# Or use a port wildcard to allow any port on that host:
MCP_ALLOWED_HOSTS=["10.1.5.62:*"]
# For a reverse-proxy hostname:
MCP_ALLOWED_HOSTS=["mcp.example.com"]
PermissionError: pyvenv.cfg (macOS stdio mode)
Symptom — Claude Desktop MCP logs show:
Fatal Python error: init_import_site: Failed to import the site module
PermissionError: [Errno 1] Operation not permitted: '.../.venv/pyvenv.cfg'
Cause: macOS TCC (Transparency, Consent, Control) blocks Claude Desktop from launching executables from inside ~/Documents, ~/Desktop, or ~/Downloads.
Fix (preferred): move the project out of those folders, recreate the venv, and update Claude Desktop's MCP config to the new path:
mv ~/Documents/mcp ~/mcp
cd ~/mcp/fortimanager-mcp
rm -rf .venv && uv sync
# Then update the "command" path in claude_desktop_config.json
Fix (alternative): grant Claude Desktop Full Disk Access — System Settings → Privacy & Security → Full Disk Access → add Claude. Broader permission; only use if relocation isn't feasible.

Integration Tests
Integration tests require a real FortiManager instance and are not run in CI.
# Set up environment
export FORTIMANAGER_HOST=your-fmg-host
export FORTIMANAGER_API_TOKEN=your-token
# Keep verification on; import the FortiManager CA for self-signed certs.
export FORTIMANAGER_VERIFY_SSL=true
# Run integration tests (requires live FMG)
pytest tests/integration/ -v
Note: Integration tests are verified against FortiManager 7.6.2. Some features may behave differently on older versions.
CI Workflow
The project uses GitHub Actions for continuous integration:
- Linting: ruff check on all source files
- Type checking: mypy with strict mode
- Unit tests: pytest with coverage reporting
- Python versions: 3.12+
All CI checks must pass before merging pull requests.
Code Quality
# Linting
ruff check src/
# Type checking

# Formatting
ruff format src/
Security Considerations
HTTP Authentication
When running in HTTP mode (Docker), you can secure the MCP endpoint with Bearer token authentication:
# Set in .env or environment
MCP_AUTH_TOKEN=your-secret-token
When configured, all HTTP requests (except /health) must include the Authorization: Bearer <token> header. If not set, the server runs without authentication (backwards compatible).
Environment File Permissions
Protect your .env files containing API tokens:
chmod 600 .env .env.*
Dynamic Tool Dispatch Security
In dynamic mode, the tool dispatcher validates tool names:
- Rejects private/internal functions (underscore-prefixed names)
- Validates that resolved attributes are callable
- Error responses never include request parameters (prevents credential leakage)
Safety Guardrails
The MCP server includes built-in safety checks to prevent accidental damage to managed infrastructure. Both are enabled by default.
Script Content Safety (FMG_SCRIPT_SAFETY)
Blocks dangerous CLI commands in create_script and update_script:
| Blocked Command | Risk |
|---|---|
execute factory-reset |
Wipes device configuration |
execute reboot |
Causes device outage |
execute shutdown |
Powers off device |
execute format |
Formats device disk |
execute erase-disk |
Erases device disk |
Handles FortiOS abbreviations (exec for execute) and case variations.
FMG_SCRIPT_SAFETY=strict # Default: block dangerous commands
FMG_SCRIPT_SAFETY=disabled # Allow all commands (use with extreme caution)
Policy Permissiveness Safety (FMG_POLICY_SAFETY)
Blocks overly permissive firewall policies in create_firewall_policy and update_firewall_policy. Detects policies where srcaddr=all + dstaddr=all + action=accept, which allows unrestricted traffic.
FMG_POLICY_SAFETY=strict # Default: block overly permissive policies
FMG_POLICY_SAFETY=warn # Allow but include warning in response
FMG_POLICY_SAFETY=disabled # Allow all policies
General Security
- API Tokens: Store tokens securely, never commit to version control
- SSL Verification: Enable SSL verification in production environments
- Least Privilege: Use FortiManager accounts with minimal required permissions
- Network Security: Restrict access to FortiManager management interface
- Workspace Locking: Use ADOM locking to prevent concurrent modifications
- Credential Sanitization: Device credentials are automatically stripped from API responses
