Freee Mcp is an official MCP server that enables AI agents to operate freee's cloud business software suite—accounting, payroll, invoicing, time tracking, sales, and e-signature—through a combination of MCP tools and Agent Skills that provide API references and operation recipes. The server handles OAuth 2.0 authentication with automatic token refresh, request validation against OpenAPI schemas, and supports multiple business locations with dynamic switching across five separate freee APIs. It solves the problem of integrating freee's business applications into AI workflows by separating concerns: Agent Skills inject API documentation into the agent's context for efficient guidance, while the MCP server manages secure API communication and validation.
