What the publisher says

From the Piazza repository's README, as published. We do not edit it. Read it on GitHub

mcp-piazza

<!-- mcp-name: io.github.jadenpxrk/mcp-piazza -->

A read-only Model Context Protocol server for Piazza. It works with every MCP client: Claude Code, Claude Desktop, Cursor, VS Code, Windsurf, Zed, Cline, Codex, Gemini CLI, Goose, opencode, JetBrains, LM Studio, Continue, and others.

Ask your assistant about your courses:

  • "What did I miss on Piazza this week?"
  • "Are there unresolved questions about HW3 in CSE 12?"
  • "Did anyone already ask about the midterm room?"
  • "When are the TA office hours?"
  • "What did the instructor change in @142?"

The server only reads data. It cannot post, edit, endorse, or delete.

Quick start

  1. Install uv.
  2. Log in one time. The command opens a login page in your browser:
uvx mcp-piazza login

You can also skip this step. If the server has no session, the first tool call opens the same page and shows its link.

  1. Add the server to your client. The server command is uvx with the argument mcp-piazza. For example:
claude mcp add --scope user --transport stdio piazza -- uvx mcp-piazza   # Claude Code
   codex mcp add piazza -- uvx mcp-piazza                                   # Codex CLI

See docs/clients.md for Claude Desktop, Cursor, VS Code, Windsurf, Zed, Gemini CLI, and other clients.

  1. Ask: "List my Piazza courses."

Tools, prompts and resources

Every tool accepts a course ID, a course number such as CSE 12 or cse12, or part of the course name.

Many clients show prompts as slash commands.

Shortened. The full README is on GitHub.
