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 Workday RaaS account to Claude via Composio Connect, enabling it to run Active Workers report for hiring, fetch payroll summary report for last month, export time tracking report as CSV, 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.

For example, ask Claude to:

  • "Run Active Workers report for hiring"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the Workday RaaS authorization link not work?

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

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

4. Why do Workday RaaS actions fail after they worked before?

The Workday RaaS connection can expire or lose permission.

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

5. How do I switch to a different Workday RaaS account?

Claude can manage the Workday RaaS connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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