Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Bolna account to Claude via Composio Connect, enabling it to list all voice agents available to me, initiate a call using your sales agent, get status of recent agent executions, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Bolna account

Back in Claude, ask it to connect to Bolna or give it any Bolna-related task.

For example, ask Claude to:

  • "List all voice agents available to me"
  • "Initiate a call using your sales agent"
  • "Get status of recent agent executions"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Bolna account is ready to use.

What is the Bolna Claude Connector, and what's possible with it?

The Bolna MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Bolna account. It provides structured and secure access to your Bolna voice agent platform, so your agent can perform actions like listing agents, making phone calls, managing executions, and retrieving analytics on your behalf.

  • Automated voice call initiation: Let your AI agent instantly initiate phone calls using your Bolna conversational agents, streamlining outreach and support tasks.
  • Agent and phone number management: Effortlessly fetch and list all your Bolna agents or phone numbers, making it easy to review and organize your voice assets.
  • Real-time execution monitoring: Retrieve detailed information about specific call executions or monitor all executions for a given agent to track performance and outcomes.
  • Batch processing for agents: List and manage batch operations associated with your agents, supporting bulk workflows and campaign management.
  • Agent cleanup and maintenance: Quickly delete agents or batches that are no longer needed, keeping your Bolna environment organized and up to date.

Troubleshooting

1. Why does Claude not use the Composio connector for Bolna?

The connector can show as connected, but Claude must use it in each Bolna conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Bolna again.

2. Why does Claude show an MCP server error before Bolna connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Bolna.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Bolna.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Bolna authorization link not work?

The Composio connector is one server. Your Bolna account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Bolna connection.
  • Composio creates a fresh Bolna authorization link.
  • Open that link in your browser and finish the Bolna sign-in.

4. Why do Bolna actions fail after they worked before?

The Bolna connection can expire or lose permission.

  • Ask Claude to inspect the Bolna connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Bolna account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Bolna.
  • If the action still fails with a permission error, check that the connected account has that permission in Bolna itself.

5. How do I switch to a different Bolna account?

Claude can manage the Bolna connection for you.

  • Ask Claude to disconnect or delete the current Bolna account.
  • Ask Claude to connect Bolna again.
  • Open the new Composio authorization link for Bolna.
  • Sign in with the other Bolna account in the browser.
  • After the account connects, ask Claude to retry the Bolna task.

6. Why is my Bolna connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Bolna connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Bolna tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Bolna.

FAQ

Frequently asked questions

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

Yes, you can. Claude Cowork 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 Bolna tools.

Yes, absolutely. You can configure which Bolna 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 Bolna data and credentials are handled as safely as possible.
