Connect clients

Point MCP clients at the org endpoint. Prefer the URL and headers shown in console Marshal → Tools & MCP → Connect. Use an org API key from Tokens.

Default production endpoint: https://production-api.exemplar.dev/mcp.

Cursor / Claude Code (HTTP MCP)

{
  "mcpServers": {
    "exemplar-mcp": {
      "transport": "http",
      "url": "https://production-api.exemplar.dev/mcp",
      "headers": {
        "x-api-key": "YOUR_API_KEY"
      }
    }
  }
}

For agent frameworks, use Frameworks with Marshal SDK (harness.tools()).

Per-spec MCP servers

After API → Tools import, Console lists:

• /mcp — all platform + custom tools
• /mcp/{slug} — only that imported API

Use the narrower server when you want a smaller tool catalog for a specialized agent.

Optional A2A

Orchestrators can load MCP tools for discrete actions and optionally delegate a whole turn to a connector specialist. Card and A2A URLs are under Tools & MCP → A2A. Details: Connector agents.
