Consul MCP Server

What does “Consul” MCP Server do?

The Consul MCP (Model Context Protocol) Server is a server implementation that exposes the full suite of HashiCorp Consul’s service discovery and key-value store APIs through a standardized MCP interface. By bridging AI assistants and developer tools with Consul’s data and management capabilities, it allows AI-powered workflows to query and manage services, perform health checks, manipulate KV storage, and interact with session, event, and system data. This integration enhances development workflows by enabling tasks such as dynamic service registration, real-time health monitoring, distributed key-value management, and streamlined event handling—all accessible via AI agents and LLM-based tools. The Consul MCP Server is ideal for orchestrating, auditing, and automating infrastructure components in environments where Consul is a core part of the stack.

List of Tools

The Consul MCP Server provides tools that expose the following Consul functionalities:

• Service Management: List running services, register/deregister services, get service and catalog info.
• Health Checks: Register/deregister health checks, retrieve health status for services.
• Key-Value Store: Get, list, put, and delete keys/values in Consul’s KV store.
• Sessions: List or destroy Consul sessions.
• Events: Fire events and list event history.
• Prepared Queries: Create and execute prepared Consul queries.
• Status: Get current Consul leader and peer list.
• Agent: Retrieve agent members and self information.
• System: Get system health service information.

Use Cases of this MCP Server

• Service Discovery and Management: AI agents can register, deregister, and inspect microservices in a distributed infrastructure, automating orchestration and scaling tasks.
• Real-time Health Monitoring: Automate health check registration and monitoring, enabling self-healing infrastructure or alerting through LLM-based workflows.
• Key-Value Store Automation: Use AI to query, update, or manage configuration or state data stored in Consul’s KV store, supporting use cases like feature flagging or distributed locks.
• Event-driven Automation: Fire events or respond to Consul events, enabling AI to trigger workflows or react to infrastructure changes.
• Session and Leadership Management: Automate session lifecycle or monitor cluster leader/peer status for resilience and failover operations.

Claude

1. Ensure Node.js and npm are installed.
2. Clone or install the repository and build the project (npm run build).
3. In the Claude configuration file, add the following JSON under "mcpServers":

   {
       "mcpServers": {
           "consul-mcp": {
               "command": "node",
               "args": [
                   "/ABSOLUTE/PATH/TO/PARENT/FOLDER/consul-mcp-server/build/index.js"
               ]
           }
       }
   }
   

4. Save the configuration and restart Claude.
5. Verify that the Consul MCP Server is available as a tool.

How to use this MCP inside flows

Using MCP in FlowHunt

To integrate MCP servers into your FlowHunt workflow, start by adding the MCP component to your flow and connecting it to your AI agent:

Click on the MCP component to open the configuration panel. In the system MCP configuration section, insert your MCP server details using this JSON format:

{
  "consul-mcp": {
    "transport": "streamable_http",
    "url": "https://yourmcpserver.example/pathtothemcp/url"
  }
}

Once configured, the AI agent is now able to use this MCP as a tool with access to all its functions and capabilities. Remember to change "consul-mcp" to whatever the actual name of your MCP server is and replace the URL with your own MCP server URL.

Overview

Our opinion

The Consul MCP Server provides a robust and comprehensive interface to Consul’s core APIs, making it valuable for AI-driven infrastructure automation. However, the lack of explicit prompt templates and resource definitions somewhat limits its immediate plug-and-play usability for LLM workflows. Setup instructions are only detailed for Claude, and sampling/roots support is unclear. Overall, it is a solid, practical tool for Consul users, especially those who can define their own resources/prompts.
