<!-- mcp-name: io.github.mhajder/zabbix-mcp -->

Zabbix MCP Server is a Python-based Model Context Protocol (MCP) server designed to provide advanced, programmable access to Zabbix monitoring data and management features. It exposes a modern API for querying, automating, and integrating Zabbix resources such as hosts, templates, triggers, items, problems, events, users, proxies, maintenance periods, and more. The server supports both read and write operations, robust security features, and is suitable for integration with AI assistants, automation tools, dashboards, and custom monitoring workflows.

• Retrieve problems, events, and alerts with severity filtering
• Access history and trend data for monitored items
• Monitor trigger states and problem severity
• Manage maintenance periods and scheduled downtimes
• Retrieve user macros and configuration data
• Get SLA and service information

Management Operations

• Create, update, and delete hosts, templates, and host groups (if enabled)
• Manage triggers, items, and discovery rules
• Configure maintenance periods and user macros
• Execute scripts on monitored hosts

• Optional Sentry integration for error tracking

🚀 Installation

Prerequisites

• Python 3.11 to 3.15
• Access to a Zabbix server. Versions 6.0 to 7.4 are supported - that is the range

the zabbix-utils client accepts, and it refuses to connect outside it unless ZABBIX_SKIP_VERSION_CHECK=true is set

• Valid Zabbix API token or user credentials with appropriate permissions

Quick Install from PyPI

The easiest way to get started is to install from PyPI:

# Using UV (recommended)
uvx zabbix-mcp

# Or using pip
pip install zabbix-mcp

Remember to configure the environment variables for your Zabbix instance before running the server:

# Create environment configuration
export ZABBIX_URL=https://zabbix.example.com/api_jsonrpc.php
export ZABBIX_TOKEN=your-zabbix-api-token

Install from Source

1. Clone the repository:

git clone https://github.com/mhajder/zabbix-mcp.git
cd zabbix-mcp

1. Install dependencies:

# Using UV (recommended)
uv sync

# Or using pip
pip install -e .

1. Configure environment variables:

cp .env.example .env
# Edit .env with your Zabbix URL and credentials

1. Run the server:

# Using UV (recommended)
uv run zabbix-mcp

# Or using the installed command directly
zabbix-mcp

Using Docker

A Docker image is available on GitHub Packages for easy deployment. It runs the HTTP Streamable transport on port 8000 (/mcp).

docker pull ghcr.io/mhajder/zabbix-mcp:latest

#### Open WebUI

Open WebUI 0.6.31 and later connect to the image directly; the separate MCPO image (ghcr.io/mhajder/zabbix-mcpo) is no longer published. In Open WebUI, go to Admin Settings > Integrations > External Tool Servers, add a connection of type MCP (Streamable HTTP) with the URL http://<host>:8000/mcp, and set Bearer authentication to your MCP_HTTP_BEARER_TOKEN.

🔒 Security & Safety Features

Read-Only Mode

The server supports a read-only mode that disables all write operations for safe monitoring:

READ_ONLY_MODE=true

Tag-Based Tool Filtering

You can disable specific categories of tools by setting disabled tags:

DISABLED_TAGS=alert,bills

Tool Search for Large Toolsets

FastMCP tool search can reduce prompt size for servers with many tools. When enabled, list_tools returns two synthetic tools:

• search_tools: Finds matching tools and returns their full schemas
• call_tool: Executes any discovered tool by name

Enable it with:

TOOL_SEARCH_ENABLED=true
TOOL_SEARCH_STRATEGY=bm25      # bm25 or regex
TOOL_SEARCH_MAX_RESULTS=8      # optional, default is 5

bm25 supports natural language queries, while regex uses a regex pattern input for deterministic matching.

Tool search respects existing visibility controls (read-only mode and disabled tags).

Rate Limiting

The server supports rate limiting to control API usage and prevent abuse. If enabled, requests are limited per client using a sliding window algorithm.

Enable rate limiting by setting the following environment variables in your .env file:

RATE_LIMIT_ENABLED=true
RATE_LIMIT_MAX_REQUESTS=60    # Maximum requests allowed per window (default: 60)
RATE_LIMIT_WINDOW_MINUTES=1   # Window size in minutes

If RATE_LIMIT_ENABLED is set to true, the server will apply rate limiting middleware. Adjust RATE_LIMIT_MAX_REQUESTS and RATE_LIMIT_WINDOW_MINUTES as needed for your environment.

Sentry Error Tracking & Monitoring (Optional)

The server optionally supports Sentry for error tracking, performance monitoring, and debugging. Sentry integration is completely optional and only initialized if configured.

#### Installation

To enable Sentry monitoring, install the optional dependency:

# Using UV (recommended)
uv sync --extra sentry

#### Configuration

Enable Sentry by setting the SENTRY_DSN environment variable in your .env file:

# Required: Sentry DSN for your project
SENTRY_DSN=https://[email protected]/6789

# Optional: Performance monitoring sample rate (0.0-1.0, default: 1.0)
SENTRY_TRACES_SAMPLE_RATE=1.0

# Optional: Include personally identifiable information (default: false).
# When true, tool inputs and outputs are sent to Sentry.
SENTRY_SEND_DEFAULT_PII=false

# Optional: Environment name (e.g., "production", "staging")
SENTRY_ENVIRONMENT=production

# Optional: Release version (auto-detected from package if not set)
SENTRY_RELEASE=1.2.3

# Optional: Profiling - continuous profiling sample rate (0.0-1.0, default: 1.0)
SENTRY_PROFILE_SESSION_SAMPLE_RATE=1.0

# Optional: Profiling - lifecycle mode for profiling (default: "trace")
# Options: "all", "continuation", "trace"
SENTRY_PROFILE_LIFECYCLE=trace

# Optional: Enable log capture as breadcrumbs and events (default: true)
SENTRY_ENABLE_LOGS=true

#### Features

When enabled, Sentry automatically captures:

• Exceptions & Errors: All unhandled exceptions with full context
• Performance Metrics: Request/response times and traces
• MCP Integration: Detailed MCP server activity and interactions
• Logs & Breadcrumbs: Application logs and event trails for debugging
• Context Data: Environment, client info, and request parameters

#### Getting a Sentry DSN

1. Create a free account at sentry.io
2. Create a new Python project
3. Copy your DSN from the project settings
4. Set it in your .env file

#### Disabling Sentry

Sentry is completely optional. If you don't set SENTRY_DSN, the server will run normally without any Sentry integration, and no monitoring data will be collected.

SSL/TLS Configuration

The server supports SSL certificate verification and custom timeout settings:

ZABBIX_VERIFY_SSL=true    # Enable SSL certificate verification
ZABBIX_TIMEOUT=30         # Connection timeout in seconds

Transport Configuration

The server supports multiple transport mechanisms for the MCP protocol:

#### STDIO Transport (Default)

The default transport uses standard input/output for communication. This is ideal for local usage and integration with tools that communicate via stdin/stdout:

MCP_TRANSPORT=stdio

#### HTTP SSE Transport (Server-Sent Events)

For network-based deployments, you can use HTTP with Server-Sent Events. This allows the MCP server to be accessed over HTTP with real-time streaming:

MCP_TRANSPORT=sse
MCP_HTTP_HOST=127.0.0.1        # Localhost
MCP_HTTP_PORT=8000           # Port to listen on
MCP_HTTP_BEARER_TOKEN=your-secret-token  # Optional authentication token

When using SSE transport with a bearer token, clients must include the token in their requests:

curl -H "Authorization: Bearer your-secret-token" http://localhost:8000/sse

#### HTTP Streamable Transport

The HTTP Streamable transport provides HTTP-based communication with request/response streaming. This is ideal for web integrations and tools that need HTTP endpoints:

MCP_TRANSPORT=http
MCP_HTTP_HOST=127.0.0.1        # Localhost
MCP_HTTP_PORT=8000           # Port to listen on
MCP_HTTP_BEARER_TOKEN=your-secret-token  # Optional authentication token

When using streamable transport with a bearer token:

curl -H "Authorization: Bearer your-secret-token" \
     -H "Accept: application/json, text/event-stream" \
     -H "Content-Type: application/json" \
     -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' \
     http://localhost:8000/mcp

Note: The HTTP transport requires proper JSON-RPC formatting with jsonrpc and id fields. The server may also require session initialization for some operations.

#### Health Endpoint

Both HTTP transports (sse and http) serve GET /health, which answers 200 ok when the server is handling requests. It needs no bearer token and does not contact Zabbix, so a Zabbix outage does not mark the MCP server unhealthy. The Docker image's HEALTHCHECK uses it:

curl http://localhost:8000/health
