Openfort MCP Server

Overview

The Open‑FeiShu MCP Server is a fully‑remote Model Context Protocol (MCP) implementation that replaces GitHub OAuth with FeiShu (also known as Lark) OAuth. Designed for developers who want to expose FeiShu‑based data and tooling to AI assistants such as Claude, this server eliminates the need for manual configuration while delivering a high‑performance, edge‑deployed solution on Cloudflare Workers. By handling user authentication and token refresh automatically, it frees developers from the boilerplate of OAuth flows and allows focus on building sophisticated AI experiences.

What Problem Does It Solve?

Many AI assistants rely on external data sources to enrich responses, but integrating a new platform often requires custom OAuth handling, server hosting, and careful scaling. The Open‑FeiShu MCP Server solves this by:

• Providing a ready‑to‑use, zero‑configuration gateway that authenticates users via FeiShu OAuth and issues MCP tokens on demand.
• Ensuring reliability with automatic token refresh, eliminating the need for developers to manage access lifecycles.
• Leveraging Cloudflare Workers’ edge network to deliver low‑latency, globally distributed access without provisioning dedicated infrastructure.

Core Value for AI Developers

For developers building AI assistants, this server offers a plug‑and‑play bridge to FeiShu’s rich ecosystem (documents, tasks, user profiles). Once the server is deployed, any MCP‑compatible client—Inspector, Cursor, ChatWise, or custom tooling—can connect, authenticate users through FeiShu, and immediately invoke FeiShu‑specific tools such as document creation or task querying. This eliminates the friction of building separate authentication layers and enables rapid iteration on AI‑powered workflows.

Key Features & Capabilities

• Zero‑configuration OAuth: No manual token handling; the server automatically manages lifecycles and refreshes them as needed.
• FeiShu OAuth Integration: Secure authentication flow that maps FeiShu user identities to MCP sessions.
• Cloudflare Workers Deployment: Edge‑first deployment guarantees high availability and low latency worldwide.
• Optimized Toolset: Advanced tools for document creation, nested block manipulation, and task retrieval are fine‑tuned to work seamlessly in clients like Cursor.
• Local Development Support: A lightweight local environment mirrors the production setup, simplifying testing and debugging.
• Broad Client Compatibility: Works out of the box with official MCP Inspector, Cursor’s one‑click installer, and ChatWise’s command‑line integration.

Real‑World Use Cases

• Knowledge Management: An AI assistant can read, update, and structure FeiShu documents on behalf of users, enabling dynamic knowledge bases.
• Task Automation: The server exposes FeiShu task APIs, allowing assistants to create, update, or query tasks in real time.
• Collaborative Writing: AI can suggest edits or generate content directly into FeiShu documents, leveraging nested block tools for structured output.
• Multi‑User Workflows: Because authentication is handled per FeiShu user, the same MCP server can serve multiple users with isolated permissions and data scopes.

Integration into AI Workflows

Once deployed, the server presents an SSE endpoint that MCP clients subscribe to. The typical flow is:

1. User opens the AI assistant and selects the FeiShu MCP server.
2. OAuth prompt appears; after authorization, the server issues a short‑lived MCP token.
3. Client connects to , authenticates with the token, and gains access to all FeiShu‑specific tools.
4. Assistant issues commands (e.g., “Create a new document titled Project Plan”), and the server translates them into FeiShu API calls, returning results back through the stream.

Because the server handles token refresh internally, subsequent interactions remain seamless without additional user intervention.

Unique Advantages

• Zero‑configuration experience contrasts sharply with the manual setup required by the official FeiShu MCP Server, making it accessible even to developers who are not experts in OAuth or Cloudflare tooling.
• Edge deployment on Cloudflare Workers offers superior scalability and latency compared to self‑hosted solutions.
• Deeply optimized toolset ensures that complex operations—such as creating nested document blocks—work reliably across popular MCP clients.
• Unified authentication through FeiShu OAuth provides a single source of truth for user identity, simplifying permission management
