Basic

OData is a web protocol that exposes data via HTTP in the OData V2 format. Use it to discover service metadata and work with exposed entity sets.

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 OData account to Claude via Composio Connect, enabling it to list all entity sets and schemas, query products with stock less than 10, create new sales order for customer, 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 OData 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 OData account

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

For example, ask Claude to:

  • "List all entity sets and schemas"
  • "Query products with stock less than 10"
  • "Create new sales order for customer"

It will prompt you to authenticate and authorize access.

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

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

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

Troubleshooting

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

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

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

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

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

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

3. Why does the OData authorization link not work?

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

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

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

The OData connection can expire or lose permission.

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

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

Claude can manage the OData connection for you.

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

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

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

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

Supported Tools

Every OData action and event your agent gets out of the box.

Create Entity

Create one entity or a bounded tree of new related entities in exactly one OData V2 POST.

Delete Entity

Permanently delete one metadata-keyed OData V2 entity only when metadata permits HTTP DELETE.

Get Entity

Retrieve one metadata-declared OData V2 entity by its complete typed key and optionally project selected structural properties.

Get Entity Schema

Return normalized CSDL keys, structural properties, navigation relationships, and effective restrictions for one exact entity set in the connected OData V2 service.

List Entities

Validate the connected OData V2 service and list its metadata-declared entity sets, ordered keys, and effective query and write restrictions.

Query Entities

Return exactly one bounded page from a metadata-declared OData V2 entity set using validated filtering, projection, and ordering; expansion is not supported.

Update Entity

Partially update one metadata-declared OData V2 entity through POST method tunneling with MERGE semantics; unsupported providers fail without PUT or PATCH fallback.

FAQ

Frequently asked questions

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

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