PopHIVE MCP is Yale's harmonized US public health surveillance dataset for disease, vaccination, and health outcome trends. Use it to query consistent public health signals across locations, time periods, and measures.

7 Tools

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 PopHIVE account to Claude via Composio Connect, enabling it to compare COVID vaccination trends by state, track influenza surveillance changes this season, analyze county disease outcome disparities, 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 PopHIVE account

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

For example, ask Claude to:

  • "Compare COVID vaccination trends by state"
  • "Track influenza surveillance changes this season"
  • "Analyze county disease outcome disparities"

It will prompt you to authenticate and authorize access.

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

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

The PopHIVE MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your PopHIVE account. It provides structured and secure access so your agent can perform PopHIVE operations on your behalf.

Troubleshooting

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

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

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

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

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

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

3. Why does the PopHIVE authorization link not work?

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

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

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

The PopHIVE connection can expire or lose permission.

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

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

Claude can manage the PopHIVE connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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