DevHelm MCP server

DevHelm MCP Server

Model Context Protocol (MCP) server for DevHelm — gives AI coding assistants (Cursor, Claude Desktop, Windsurf, etc.) access to your uptime monitors, incidents, alerting, and more.

Quick Start

Hosted (recommended)

Use the hosted server at mcp.devhelm.io. Two connection modes:

Bearer auth:

URL: https://mcp.devhelm.io/mcp
Authorization: Bearer <your-api-token>

API key in URL (for clients that only accept a URL):

URL: https://mcp.devhelm.io/<your-api-token>/mcp

Local (stdio)

pip install devhelm-mcp-server
export DEVHELM_API_TOKEN=your-token
devhelm-mcp-server

Or with uvx (no install required):

export DEVHELM_API_TOKEN=your-token
uvx devhelm-mcp-server

Cursor / Claude Desktop

Add to your MCP config:

{
  "mcpServers": {
    "devhelm": {
      "url": "https://mcp.devhelm.io/<your-api-token>/mcp"
    }
  }
}

Webhook Testing	inboxes list, get, create, update, activity; wait (≤25 s), latest, list/get events

Delete, publish and rollback return {status: "confirmation_required", changes, confirmationToken} first; call again with confirmation_token after the user agrees. Tokens are HMACs signed by the server process (set DEVHELM_MCP_CONFIRMATION_SECRET so every replica shares the key) and last 15 minutes. Errors come back as isError with every ErrorResponse field and a sentence for the agent.
