Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "piazza": {
      "command": "uvx",
      "args": [
        "mcp-piazza"
      ],
      "env": {

        "PIAZZA_MIN_INTERVAL": "your-value",
        "PIAZZA_CACHE_TTL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add piazza --env PIAZZA_EMAIL=your-value --env PIAZZA_PASSWORD=your-value --env PIAZZA_COOKIE_FILE=your-value --env PIAZZA_ANONYMIZE_STUDENTS=your-value --env PIAZZA_FENCE_CONTENT=your-value --env PIAZZA_MIN_INTERVAL=your-value --env PIAZZA_CACHE_TTL=your-value -- uvx mcp-piazza

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "piazza": {
      "type": "stdio",

Common questions

Is MCP Piazza safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: PIAZZA_PASSWORD

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

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

Install uv.
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.

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.

Ask: "List my Piazza courses."

Tools, prompts and resources

Tool	Purpose
`list_courses`	List your courses with ID, course number, term, role, active status, and folders.
`get_course_info`	Get the course page: description, syllabus, office hours, general information, and staff with emails.
`get_unread_counts`	Count unread posts in each active course.
`recent_activity`	List posts with new activity since a time (`24h`, `7d`, `2026-10-01`), in all active courses or one course.
`list_posts`	List post summaries. Filters: `all`, `unread`, `following`, `unresolved`, `unanswered`, `mine`, `starred`. Optional `folder` and paging.
`search_posts`	Search posts by keywords in one course or in all active courses.
`get_post`	Read one full thread: question, instructor answer, student answer, followups, replies, and poll data.
`get_posts`	Read up to 20 full threads in one call.
`get_post_history`	Show every version of a post, with a diff between versions.
`list_instructor_notes`	List notes and polls written by instructors.
`get_attachment`	Open an image or file from a post. The model can see images.
`get_course_stats`	Get the data from the course Statistics page.

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

Prompt	Purpose
`catch_up`	Read all posts since a time and summarize them, with actions for you.
`before_asking`	Find out if a question was already asked and answered.
`exam_prep`	Read all posts about an exam or topic and collect the facts.

Many clients show prompts as slash commands.

`piazza-exam-prep`	The `exam_prep` steps.
`piazza-before-asking`	The `before_asking` steps.

Skills work in Claude Code, Cursor, Codex, opencode, and other agents. They need the server. To install them:

npx skills add jadenpxrk/mcp-piazza

Resource	Content
`piazza://courses`	Your courses
`piazza://courses/{course_id}/posts/{number}`	One full thread

See docs/tools.md for parameters and output fields, and docs/workflows.md for examples.

Authentication

Piazza has no public API. This server uses piazza-api, which logs in as the Piazza website does.

Method	How	Use it when
Login page	`mcp-piazza login`, or the link from the first tool call	Most people. The page offers the three methods below.
Browser session	`mcp-piazza login --browser`	You are logged in to piazza.com in Chrome, Arc, Brave, Edge, Firefox, Safari, Chromium, Vivaldi, or Opera. This works with school SSO.
Password	`mcp-piazza login --password`	You want to type your email and password in the terminal.
Session cookie	`mcp-piazza login --cookie`	You want to paste the `session_id` cookie from the browser developer tools.
Environment variables	`PIAZZA_EMAIL`, `PIAZZA_PASSWORD`	You want automatic login when the session expires.

All methods save only the session cookies to ~/.config/mcp-piazza/cookies.json with file mode 600. They do not save your password. When the session expires, the next tool call opens the login page again. mcp-piazza logout deletes the session.

Configuration

Variable	Default	Purpose
`PIAZZA_EMAIL`	none	Account email for automatic login.
`PIAZZA_PASSWORD`	none	Account password for automatic login.
`PIAZZA_COOKIE_FILE`	`~/.config/mcp-piazza/cookies.json`	Path of the saved session.
`PIAZZA_ANONYMIZE_STUDENTS`	`false`	Replace student names with pseudonyms.
`PIAZZA_FENCE_CONTENT`	`true`	Mark post text as untrusted data.
`PIAZZA_KEEP_UNREAD`	`false`	Mark unread posts unread again after the server reads them.
`PIAZZA_MIN_INTERVAL`	`0.5`	Minimum seconds between Piazza requests.
`PIAZZA_CACHE_TTL`	`60`	Seconds to keep feeds and posts in memory. `0` turns off the cache.

See docs/configuration.md for examples and the command line.

Privacy and safety

Read-only. The server has no tools that change Piazza data. The only write is the optional PIAZZA_KEEP_UNREAD restore.
Prompt-injection fencing. Other course members write the post text. The server puts that text between << >> markers, and the server instructions tell the model to treat it as data.
Student pseudonyms. When PIAZZA_ANONYMIZE_STUDENTS=true, other students show as Student 3f2a1c. Staff keep their names. Your own posts show as you.
Local only. The server runs on your computer. It sends your cookies only to piazza.com.

See docs/privacy.md for the full model and its limits.

Development

uv sync

uv run pytest # offline tests, no Piazza account needed uv run ruff check src tests uv run ruff format src tests uv run mypy src

See AGENTS.md for the project layout and rules.

Limitations

Piazza can change its internal API at any time. If tools fail after a Piazza update, see docs/troubleshooting.md.
When the server reads a full post, Piazza marks the post as read and counts a view, as the website does. Set PIAZZA_KEEP_UNREAD=true to mark unread posts unread again.
The course page files and links (the Resources tab) are not available. get_course_info shows the names of the resource sections only.
Piazza does not document the poll format. get_post returns the poll data as Piazza sends it.
Some instructors hide the Statistics page. For those courses, get_course_stats returns an error.
