🧪 MCP Playground API

Call MCP Server Tool

Executes a tool call on an MCP server — the playground API for testing and debugging tools by directly invoking them with parameters.

The target server is identified by the X-Enkrypt-MCP-Registry-Server header — the gateway fetches its config from GET /mcp-registry/get-server using your apikey and uses the cloud’s 200/401/403 response as the authentication gate.

The request body carries the tool invocation: tool_name (required) and optional tool_arguments.
