Humanloop is a platform for building and refining AI applications through user feedback and data annotation. It helps teams iterate on language model performance for more accurate and effective AI solutions.

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 Humanloop account to Claude via Composio Connect, enabling it to create a new project for sentiment analysis, delete your old prototype project permanently, list all experiments for project pr_12345, 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.

Connecting Humanloop to Claude Web, Desktop, and Cowork

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Humanloop account

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

For example, ask Claude to:

  • "Create a new project for sentiment analysis"
  • "Delete your old prototype project permanently"
  • "List all experiments for project pr_12345"

It will prompt you to authenticate and authorize access.

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

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

The Humanloop MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Humanloop account. It provides structured and secure access to your Humanloop projects, so your agent can perform actions like creating projects, managing experiments, and analyzing session data on your behalf.

  • Project creation and management: Let your agent spin up new Humanloop projects, add descriptions, and organize them for streamlined AI development.
  • Automated project deletion: Direct your agent to permanently remove projects, cleaning up experiments or outdated initiatives with a single command.
  • Experiment tracking and analysis: Easily retrieve and review all experiments within a project, including configurations, status, and results for continuous iteration and improvement.
  • Session history and monitoring: Ask your agent to list and analyze sessions for a given project, giving you insight into user interactions, datapoints, and evaluation history.

Troubleshooting

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

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

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

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

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

  • 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 Humanloop.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Humanloop authorization link not work?

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

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

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

The Humanloop connection can expire or lose permission.

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

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

Claude can manage the Humanloop connection for you.

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

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

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

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Humanloop 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 Humanloop.

FAQ

Frequently asked questions

With a standalone Humanloop MCP server, the agents and LLMs can only access a fixed set of Humanloop tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Humanloop 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 Humanloop tools.

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