Dokümantasyon

CL Chef Server MCP Server

A Model Context Protocol (MCP) server that exposes the Chef Infra Server API for generic, stateless, multi-tenant API operations.

Overview

This MCP is an integration server for Chef Infra Server and follows Curious Layer standards:

  • Stateless and multi-tenant by design
  • Per-request authentication (no shared in-memory auth/session state)
  • Generic API coverage for all Chef Server endpoints via tool calls

Authentication

All tenant-facing tools require authentication input on every call.

Chef Signature Auth (default)

Use this auth payload format in auth_data:

{
  "auth_type": "chef-signature",
  "user_id": "pivotal",
  "private_key": "-----BEGIN RSA PRIVATE KEY-----\n...\n-----END RSA PRIVATE KEY-----",
  "auth_version": "1.3",
  "chef_version": "18.0.0",
  "server_api_version": "1"
}

Notes:

  • private_key_base64 can be used instead of private_key.
  • auth_version supports 1.3 (recommended) and 1.0.

Basic Auth (for endpoints like /_stats)

{
  "auth_type": "basic",
  "basic_username": "statsuser",
  "basic_password": "your-password"
}

This server exposes dedicated tools per endpoint functionality (instead of a generic wrapper).
