What is Tencent Lexiang?

Tencent Lexiang is an MCP (Model Context Protocol) server that enables AI assistants to search, read, create, edit, and organize content in Tencent Lexiang knowledge bases. It is designed for teams using Tencent Lexiang, an AI-powered enterprise knowledge base, to unlock private knowledge through AI conversations.

How to use Tencent Lexiang?

Two authentication methods are supported: OAuth login (recommended) or manual access token. The quickest way is to log in to Lexiang, visit https://lexiangla.com/mcp, and click “Open in Cursor” or “Open in VS Code”.

FAQ from Tencent Lexiang

What authentication methods does Tencent Lexiang MCP support?

It supports OAuth login (recommended, no token creation needed) and manual access token configuration via URL parameter.

Why do I get an “authorization required” error?

Ensure you have obtained correct configuration from https://lexiangla.com/mcp, refresh the OAuth flow in CodeBuddy, and verify the company_from parameter in the URL.

Why can’t I find my knowledge base?

MCP only accesses knowledge bases that you have permission to view. Check your access rights in Tencent Lexiang.

Why does file upload fail?

File upload requires three steps: call apply_upload to get an upload URL, perform an HTTP PUT upload (outside MCP), and then call commit_upload to confirm.

Why does the AI create a new document instead of updating an existing one?

Be explicit in your prompt (e.g., “update the original document”). The server supports block-level editing for precise in-place updates.
