Mist Server

Reliable access to Juniper Mist from your AI tools, without writing code.

This project provides a production-grade MCP server that wraps the Mist API via mistapi, so Cursor and VS Code can call Mist safely through standard MCP tools.

Why this exists

MCP servers make API access simple and consistent for AI tools. This server centralizes connection and auth, validates configuration at startup, and exposes a tool registry so non-coders can use Mist through natural language.

Prerequisites

• Python 3.10+
• A Mist API token

Install

No manual install required for end users. The MCP runner bootstraps the local virtual environment on first run.

Configure

Create a .env file in this folder (see mist.env.example):

MIST_API_TOKEN=your_token_here
MIST_API_HOST=https://api.mist.com
MIST_API_TIMEOUT_SECONDS=30

Important: MIST_API_HOST must be the base host (no /api/v1). The server will call the Mist “self” endpoint at startup and exit immediately if the host or token is invalid.

Local use (Cursor)

1. Open this project in Cursor.
2. Make sure a mcp.json file exists at .cursor/mcp.json. This repo already provides it, so you usually do not need to change anything.
3. Use the configuration below:

{
  "mcpServers": {
    "mist": {
      "command": "${workspaceFolder}/run-mcp.sh",
      "args": [],
      "envFile": "${workspaceFolder}/.env",
      "transport": "stdio"
    }
  }
}

4. Restart Cursor (or reload the window).
5. Ask Cursor to call Mist tools, e.g. “list my orgs”.

Local use (VS Code)

1. Open this project in VS Code.
2. Make sure a mcp.json file exists at .vscode/mcp.json. This repo already provides it, so you usually do not need to change anything.
3. Reload the window and use your MCP client to call Mist tools.

Usage

• A tool registry is generated from the Mist SDK.
• Use mist_search_tools to find tools by keyword.
• Use mist_list_groups to discover tool groups and filter search.
• Use mist_list_methods to list methods in a group.
• Use mist_describe_tool to see parameters and details.
• Use mist_call_tool to execute by name with args/kwargs.
• Regenerate the registry after SDK updates via scripts/generate_tools.py.
