FAQ from stack-exchange-mcp

What does stack-exchange-mcp do?

It bridges Stack Overflow with LLM tools, giving AI coding assistants live access to Stack Overflow content and enabling users to post questions and answers through the same interface.

What are the prerequisites to use stack-exchange-mcp?

Node.js 18+ (ES2022), a Stack Exchange API key, and a registered Stack Apps application for write access.

Can I write to Stack Overflow using stack-exchange-mcp?

Yes, but write operations (posting questions, answers, comments, editing posts) require Stack Exchange OAuth 2.0 authentication. Read operations do not need authentication.

What read operations are available?

You can search and fetch questions, get answers for specific questions, fetch comments on posts, browse and search tags, and retrieve user information.

How is authentication handled?

The server uses Stack Exchange OAuth 2.0. You register an app on Stack Apps, configure OAuth credentials in the .env file, and the server handles the OAuth flow when write operations are requested.
