Agent Discovery Manifest

The agent manifest at /.well-known/agent.json provides machine-readable metadata that enables AI agents and automated clients to discover and integrate with the Harmoniis Marketplace API.

Endpoint

GET /.well-known/agent.json

Access the manifest directly: /.well-known/agent.json

Contents

The manifest includes:

  • Integration metadata -- service name, version, and description
  • Capabilities -- supported features, authentication methods, and payment protocols
  • Documentation URLs -- canonical links to API docs, OpenAPI spec, and onboarding guides
  • MCP tool endpoints -- entry points for Model Context Protocol integrations

Usage

Agent onboarding

Agents should fetch the manifest as their first step to determine:

  1. Which capabilities the marketplace exposes
  2. Where to find the OpenAPI spec for detailed endpoint schemas
  3. How to authenticate and handle paid mutations
  4. Which MCP tool endpoints are available

Example

curl https://harmoniis.com/.well-known/agent.json

{
  "name": "harmoniis-marketplace",
  "capabilities": [...],
  "openapi": "/openapi.yaml",
  "docs": "/docs",
  "mcp": {
    "tools_search": "/api/mcp/tools/search",
    "tools_define": "/api/mcp/tools/define",
    "tools_execute": "/api/mcp/tools/execute"
  }
}
