Introduction

Grok is xAI's assistant, and its bot builder lets you create a personal agent that holds context, runs skills, and connects to the apps you already use through plugins.

This guide explains how to connect Polar Signals to a Grok bot using Composio Connect, which handles OAuth, token refresh, and reliability so you do not have to. You add Composio as a plugin, authenticate once, then ask your bot to work with Polar Signals in plain language.

Why use Composio?

Composio exposes 1,700+ apps to your Grok bot through a single connection, so you get:

  • Connect to 1,700+ apps with on-demand tool loading, so you do not fill your context window with unnecessary tool definitions.
  • Use programmatic tool calling through a remote workbench, letting the model write its own code to handle complex tool chaining. This reduces back-and-forth for frequent tool calls.
  • Handle large tool responses outside the model context to keep conversations lean.

Connecting Polar Signals to Grok Bot

Once Grok Bot is set up, you connect Polar Signals entirely from its interface, and the whole flow takes under a minute.

Set up Grok Bot

Get access. Grok Bot is included with Cursor Ultra, Cursor Premium Teams, and SuperGrok Heavy. Get the desktop app for macOS or Windows from x.ai/bot and sign in. An iPhone companion app is also available, and your bots sync across devices.

Create a bot. Pick a suggested role or define your own, then give it a short name, one primary job, and a short description of how it should work. Focused bots work best, because a clear role gives the bot more useful context over time.

Connect Polar Signals

1. Add the Composio plugin

Click the button. The Composio listing on x.ai opens and launches Grok Bot for you. If the app does not open on its own, click Add to Grok Bot.

2. Authenticate

Go to the Installed section and click the Composio entry. You'll see its connector and skills listed.

Click Authenticate. You'll be taken to the Composio consent screen. Review the access it requests and click Authorize. Composio handles the OAuth handshake for you, so you never touch API keys or tokens.

3. Connect your Polar Signals account

Back in the chat, ask your bot to connect to Polar Signals or give it any Polar Signals task.

For example, ask it to:

  • "Summarize top CPU hotspots last week"
  • "List regressions across releases for auth-service"
  • "Create optimization checklist for auth-service hotspots"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in your Grok bot, and your Polar Signals account is ready to use.

What is Grok Bot?

Grok is xAI's assistant, available as a chat interface and a bot builder for creating personal agents that run skills and connect to external apps.

With Composio Connect, your Grok bot can securely access apps like Polar Signals through MCP without you sharing account credentials directly with the agent.

What is the Polar Signals MCP server, and what's possible with it?

The Polar Signals MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Polar Signals account. It provides structured and secure access to your continuous profiling projects and performance data, so your agent can list projects, explore profile types and labels, analyze flame graphs, inspect function relationships, and identify optimization opportunities on your behalf.

  • Project and profile discovery: Have your agent list accessible projects and find the profile types available for performance analysis.
  • Flame graph analysis: Let the agent query flame graphs as call trees to investigate where applications spend their time.
  • Function performance ranking: Direct your agent to compare functions in a flat table sorted by cumulative time and spot likely optimization targets.
  • Caller and callee inspection: Instruct your agent to examine which functions call a chosen function and which functions it calls.
  • Label and source analysis: Have your agent explore profile labels and their values, then retrieve per-line profiling data for a specific source file.

Way Forward

Now that Polar Signals is connected, extend your setup by connecting the other apps you already use every day, so your Grok bot can run true cross-app workflows end to end.

  • Connect Calendar to turn threads into scheduled meetings automatically.
  • Connect Slack or Teams to post summaries, approvals, and alerts where your team works.
  • Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs.
  • Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps.

Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single connection, your bot can coordinate multiple tools safely and reliably in one conversation.

FAQ

Frequently asked questions

With a standalone Polar Signals MCP server, the agents and LLMs can only access a fixed set of Polar Signals tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Polar Signals and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Grok Bot fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Polar Signals tools.

Yes, absolutely. You can configure which Polar Signals scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Polar Signals data and credentials are handled as safely as possible.
