Arcade Workers API

Register, manage, health-check, and authorize workers that host Arcade toolkits or MCP servers behind the Arcade Engine. Self-hosted workers let customers keep tool execution (and end-user tokens) inside their own perimeter.

Arcade Workers API is one of 9 APIs that arcade-dev publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

This API exposes 1 machine-runnable capability that can be deployed as REST, MCP, or Agent Skill surfaces via Naftiko and 2 JSON Schema definitions.

Tagged areas include Workers, MCP, Infrastructure, and Agents. The published artifact set on APIs.io includes API documentation, an OpenAPI specification, sample payloads, 1 Naftiko capability spec, and 2 JSON Schemas.
