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 Peopledatalabs account to Claude via Composio Connect, enabling it to enrich this email with full person profile, standardize and clean this company name, get detailed info for the skill 'Python', 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 Peopledatalabs account

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

For example, ask Claude to:

  • "Enrich this email with full person profile"
  • "Standardize and clean this company name"
  • "Get detailed info for the skill 'Python'"

It will prompt you to authenticate and authorize access.

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

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

The Peopledatalabs MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Peopledatalabs account. It provides structured and secure access to rich B2B data, so your agent can enrich profiles, standardize company details, validate customer information, and perform advanced searches with ease.

  • Comprehensive person data enrichment: Automatically enhance individual profiles using identifiers like email, phone, or full name combined with company or location data.
  • Company data validation and enrichment: Instantly verify and enrich company details with firmographics, employee counts, and standardized fields to power your workflows.
  • Advanced person search and filtering: Leverage Elasticsearch-powered queries to find the exact professional profiles you need using job title, skills, experience, and more.
  • Data cleaning and standardization: Cleanse and structure raw company, school, or location data to maintain high-quality records in your systems.
  • Skill and job title enrichment: Provide context and standardized information for job titles or professional skills to improve analytics and targeting.

Troubleshooting

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

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

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

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

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

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

3. Why does the Peopledatalabs authorization link not work?

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

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

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

The Peopledatalabs connection can expire or lose permission.

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

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

Claude can manage the Peopledatalabs connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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