Grupy MCP

Grupy connects your AI assistant to the WhatsApp groups on your own account. Ask for a summary of what you missed. Search past summaries. Review join requests. Turn groups on or off.

This repository holds the connection files for Grupy MCP. It has no server code. The server runs at `https://mcp.grupy.chat/mcp` (Streamable HTTP).

What Grupy MCP does

• It summarizes one group or many groups for a time range.
• It reads and searches the stored messages of your groups, when you allow it.
• It lists your groups, your WhatsApp numbers, your summaries, and your Fathom meetings.
• It shows join requests and join request decisions. It can approve or reject a request, when you allow it.
• It turns groups on or off and changes summary schedules, when you allow it.
• It exports a member list after you give export consent in the dashboard.

What Grupy MCP does not do

• It does not send WhatsApp messages.
• It does not add or remove members. It does not change admins.
• It does not read personal chats. It works only with groups of the WhatsApp account that you link.

Connect

You need a Grupy account and a linked WhatsApp number. Sign up at https://grupy.chat.

The server URL is the same for both methods:

https://mcp.grupy.chat/mcp

Never put an access key in a file that you share or commit. Use an environment variable.

Permissions

Each connection has optional permissions. You turn them on in the Grupy dashboard on the MCP page. Tools that need a permission do not appear until you turn that permission on.

Tools

Grupy MCP has 28 tools. Every tool has a title and the readOnlyHint, destructiveHint, and openWorldHint annotations. Read tools set readOnlyHint to true. A tool that cannot be undone sets destructiveHint to true.

Always available

With the Read messages permission

With the Manage join requests permission

With the Manage groups permission

Prompts

Client setup

Each block below uses the sign-in method unless it says otherwise. Replace GRUPY_ACCESS_KEY with an environment variable that holds your access key.

Claude (claude.ai, Claude Desktop, mobile)

1. Open Customize > Connectors > Add custom connector.
2. Enter https://mcp.grupy.chat/mcp.
3. Sign in to Grupy and approve.

Claude Code

claude mcp add --transport http grupy https://mcp.grupy.chat/mcp

Then sign in with /mcp inside Claude Code, or run claude mcp login grupy in a shell.

Access key:

claude mcp add --transport http grupy https://mcp.grupy.chat/mcp \

--header "Authorization: Bearer $GRUPY_ACCESS_KEY"

ChatGPT

1. Open ChatGPT Plugins and choose Add custom MCP server.
2. Enter https://mcp.grupy.chat/mcp and choose OAuth.
3. Create the plugin, sign in to Grupy, and approve.

ChatGPT does not send access keys, so use the sign-in method. What you can add depends on your plan and workspace settings.

Cursor

Add to Cursor

Or add this to ~/.cursor/mcp.json:

{

"mcpServers": { "grupy": { "url": "https://mcp.grupy.chat/mcp" } } }

Access key:

{

"mcpServers": { "grupy": { "url": "https://mcp.grupy.chat/mcp", "headers": { "Authorization": "Bearer ${env:GRUPY_ACCESS_KEY}" } } } }

This repository is also a Cursor plugin. See .cursor-plugin/plugin.json.

VS Code (GitHub Copilot)

Install in VS Code

Or add this to .vscode/mcp.json:

{

"servers": { "grupy": { "type": "http", "url": "https://mcp.grupy.chat/mcp" } } }

Access key:

{

"inputs": [ { "type": "promptString", "id": "grupy-key", "description": "Grupy access key", "password": true } ], "servers": { "grupy": { "type": "http", "url": "https://mcp.grupy.chat/mcp", "headers": { "Authorization": "Bearer ${input:grupy-key}" } } } }

In a Copilot Business or Enterprise organization, an administrator must allow MCP servers.

Gemini CLI

gemini extensions install https://github.com/ai-builders-id/grupy-mcp

Or add the server by hand:

gemini mcp add --transport http grupy https://mcp.grupy.chat/mcp

Access key:

gemini mcp add --transport http --header "Authorization: Bearer $GRUPY_ACCESS_KEY" grupy https://mcp.grupy.chat/mcp

Codex (CLI and IDE extension)

codex mcp add grupy --url https://mcp.grupy.chat/mcp

codex mcp login grupy

Access key. Add this to ~/.codex/config.toml:

[mcp_servers.grupy]

url = "https://mcp.grupy.chat/mcp" bearer_token_env_var = "GRUPY_ACCESS_KEY"

Cline

Add this to cline_mcp_settings.json:

{

"mcpServers": { "grupy": { "type": "streamableHttp", "url": "https://mcp.grupy.chat/mcp", "disabled": false, "autoApprove": [] } } }

Always set "type": "streamableHttp". Without it, Cline uses the old SSE transport. For an access key, add "headers": { "Authorization": "Bearer " }. Cline can also read llms-install.md to set up Grupy for you.

Zed

Add this to settings.json:

{

"context_servers": { "grupy": { "url": "https://mcp.grupy.chat/mcp" } } }

For an access key, add "headers": { "Authorization": "Bearer " }.

Goose

Add to Goose

Or add this to ~/.config/goose/config.yaml:

extensions:

grupy: name: Grupy type: streamable_http uri: https://mcp.grupy.chat/mcp enabled: true timeout: 300

OpenClaw

openclaw mcp set grupy '{"url":"https://mcp.grupy.chat/mcp","transport":"streamable-http","auth":"oauth","oauth":{"scope":"grupy:read"}}'

openclaw mcp login grupy

Access key. Add this to your OpenClaw configuration:

{

"mcp": { "servers": { "grupy": { "url": "https://mcp.grupy.chat/mcp", "transport": "streamable-http", "headers": { "Authorization": "Bearer ${GRUPY_ACCESS_KEY}" } } } } }

Always set "transport": "streamable-http". With "auth": "oauth", OpenClaw ignores a static Authorization header. The skills/grupy folder is an OpenClaw skill that teaches the agent how to use the tools.

Hermes Agent

Add to Hermes

Or add this to ~/.hermes/config.yaml:

mcp_servers:

grupy: url: "https://mcp.grupy.chat/mcp" auth: oauth

Then run hermes mcp login grupy. For an access key, replace auth: oauth with headers: { Authorization: "Bearer ${GRUPY_ACCESS_KEY}" }. The skills/grupy folder is also a Hermes skill.

Other clients

Any client that supports remote MCP over Streamable HTTP can connect. Enter the server URL. Use the sign-in method, or send the Authorization: Bearer header. LM Studio: add Grupy. Setup guides for more clients are at https://grupy.chat/en/mcp.

Privacy and data

• Grupy works only with groups of the WhatsApp account that you link. It does not read personal chats.
• Before Grupy sends chat text to an AI model to write a summary, it replaces numbers and names with pseudonyms.
