What is this?

The TimelinesAI MCP server is a remote control for your real WhatsApp inbox inside TimelinesAI. Connect once with your TimelinesAI login, then your AI assistant gains 34 tools across chat discovery, messaging, triage (labels + assignments) and workspace introspection, for both regular WhatsApp numbers (connected by QR code) and WhatsApp Business API (WABA) numbers.

It's a hosted server: nothing to install, no API keys. Your assistant connects to https://mcp.services.timelines.ai/mcp and you sign in once.

No sandbox. Writes are real and visible to your contacts. Recipients cannot tell whether a message came from the UI or from an AI assistant: it's all just you.

Requirements

• A TimelinesAI account with at least one connected WhatsApp number in your workspace. Without a connected number, most tools return empty results or errors. The MCP is a remote control for your real inbox, not a sandbox.

• An AI assistant that supports remote MCP servers (all the clients below do).

Quick setup (~1 min)

Server URL for every client: https://mcp.services.timelines.ai/mcp

ChatGPT

Open the TimelinesAI plugin in ChatGPT, click Connect and sign in with your TimelinesAI account. Then ask: "@TimelinesAI what needs me today?"

Claude (claude.ai and Claude Desktop)

In Claude, open Customize → Connectors → Add custom connector, paste the server URL and sign in with your TimelinesAI account.

Claude Code

claude mcp add --transport http timelinesai https://mcp.services.timelines.ai/mcp

Claude Code opens a browser tab the first time a tool is used. Sign in with your TimelinesAI account.

Prefer a plugin? /plugin marketplace add InitechSoftware/whatsapp-mcp-by-timelinesai, then /plugin install timelinesai-whatsapp@timelinesai. The plugin launches a local proxy, so it needs Node.js 18+; the command above doesn't.

Cursor

Add to Cursor (one click), or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "timelinesai": {
      "url": "https://mcp.services.timelines.ai/mcp"
    }
  }
}

The sign-in window opens on the first tool call.

Codex

Add to ~/.codex/config.toml:

[mcp_servers.timelinesai]
url = "https://mcp.services.timelines.ai/mcp"

Then run codex mcp login timelinesai once and approve in the browser. Codex doesn't start the sign-in on its own.

Grok Build

grok mcp add timelinesai https://mcp.services.timelines.ai/mcp

Then type /mcps, select timelinesai and press i to sign in. Grok Build doesn't start the sign-in on its own.

Any other MCP client

Add https://mcp.services.timelines.ai/mcp as a remote server (Streamable HTTP) and sign in when prompted.

See examples/ for ready-to-copy config files.

First thing to try

After connecting, ask your assistant:

"What needs me today?"

or, for a tour:

"What tools does the timelinesai MCP server expose? Group them by purpose and give me one example prompt per group."

Tool catalog (34 tools)

Two parallel sets of tools (one for regular WhatsApp numbers connected by QR code, one for WhatsApp Business API (WABA) numbers) plus three workspace tools shared by both. Use the set that matches the number: workspace_whatsapp_accounts lists QR numbers, waba_accounts lists WABA numbers.

Workspace: 3 tools

Read-only introspection. Cheap to call. Shared by both sets.

WhatsApp (QR-connected numbers): 14 tools

Chat discovery + inspection: 4 tools

Browse and read. No writes.

Messaging writes: 4 tools

Quota-consuming. Same monthly messaging budget as the TimelinesAI UI.

Chat mutations: 6 tools

State + triage operations on chats. Idempotent label and assign ops.

WhatsApp Business API (WABA): 17 tools

Accounts + chat discovery: 5 tools

Browse and read. No writes.

Templates: 2 tools

Messaging writes: 4 tools

Template sends incur a Meta charge. Free text only works while the chat's service window is open.

Chat mutations: 6 tools

State + triage operations on WABA chats. After any mutation, waba_chat_details returns the authoritative state.

→ Full schemas and example prompts: docs/tools.md

How sign-in works

The server uses OAuth. The first time your assistant connects, a browser window opens on TimelinesAI. Sign in to your TimelinesAI account and approve access. Your assistant keeps the sign-in, so later sessions reconnect without asking.

If you're already signed in to TimelinesAI in your browser, approval can take a single click.

Every action runs as you: your role's permissions in TimelinesAI apply to MCP calls exactly as they apply to UI actions.

Safety + production behavior

⚠️ This MCP server controls a real WhatsApp inbox. Read this section before sending writes.

• Messages sent via MCP are indistinguishable from messages sent in the UI. Recipients cannot tell.

• Writes are real and immediate. No undo. Confirm before bulk actions.

• Quota is shared with UI usage: MCP messages draw from the same monthly messaging budget. Call workspace_quotas to see headroom.

• WABA template messages are charged by Meta. waba_start_chat and waba_chat_send_template send approved templates, which Meta bills for. Free-text waba_chat_send_message only works while the chat's service window is open.

• No sandbox mode. Practice on your own number first if you're unsure.

• Without a connected WhatsApp number, most tools return empty results or errors. Connect a number in TimelinesAI first.
