freee FAQs

Question 1

How does freee Remote MCP Server ensure security for my freee data?

Accepted Answer

Security is handled through a two-stage OAuth process: one between your MCP client and the Worker, and another between the Worker and the freee API. Crucially, freee access tokens are stored securely within Cloudflare Durable Objects and are never exposed directly to the MCP client, mitigating risks.

Question 2

What is the Model Context Protocol (MCP) and how does it relate to freee?

Accepted Answer

The Model Context Protocol (MCP) is a protocol that allows clients (e.g., Cursor) to interact with the freee API through this server. It standardizes the way these clients consume and manage data from freee, abstracting the complexities of the underlying freee API.

Question 3

Is it difficult to deploy the freee Remote MCP Server?

Accepted Answer

No, it's designed for ease of deployment. It offers a 'one-click deploy' option to Cloudflare Workers, which automates GitHub integration, build processes, and provisioning of necessary KV namespaces. You only need to configure freee OAuth details and environment variables post-deployment.

Question 4

What Cloudflare resources does freee Remote MCP Server use?

Accepted Answer

This server leverages Cloudflare Workers for execution, KV namespaces (`OAUTH_KV`) for storing OAuth provider state, and Cloudflare Durable Objects (`FREEE_TOKEN_DO`, `PENDING_STATE_DO`) for atomic state management and securely storing freee access/refresh tokens per user.

Question 5

What is freee Remote MCP Server?

Accepted Answer

It's a server deployed on Cloudflare Workers designed to provide secure remote access to the freee API. It utilizes the Model Context Protocol (MCP) and implements OAuth 2.1 + PKCE for robust authentication, making it ideal for client applications like Cursor.
