How to connect OData MCP with ChatGPT

ChatGPT can take action across your apps and files, stay with a project for hours, and turn a goal into finished materials like sheets, slides, and docs, not just answers.

In this guide, I will explain the easiest and most secure way to connect your OData account to ChatGPT via Composio Connect, so it can discover service metadata, list entity sets and schemas, query and filter your entity data, and create, update, and delete records through natural language commands without ever putting your account credentials at risk.

Why use Composio over default connectors?

  • Apps with read and write access. Default connectors mostly can read your data. Composio's OData integration lets ChatGPT take actions like creating drafts, sending updates, labeling records, and more.
  • 1,500+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
  • One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
  • Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
  • Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

Prerequisites

Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.

Step-by-step: Connect OData to ChatGPT

1. Install the Composio plugin

Click the button. ChatGPT opens the Composio plugin page. Click Install plugin.

Install in ChatGPT

You can also find it inside ChatGPT: go to Settings, open Plugins, search the marketplace for Composio, and click Install plugin.

2. Authenticate

After you install, ChatGPT asks you to authenticate with Composio. Log in and click Allow access to authorize ChatGPT to use your Composio account.

3. Start using Composio

That is it. Composio tools are now available in ChatGPT. Type @Composio followed by your request, for example @Composio find unread OData messages and summarize them, and it will run the actions you authorize. On first use it asks you to authorize OData.

Option 2: Add Composio as an MCP server

If you cannot use the plugin marketplace, add Composio as a custom MCP server instead.

1. Open the MCP settings

In ChatGPT, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab.

2. Add the server

Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
ChatGPT Add server dialog with the name Composio, type Streamable HTTP, and the Composio MCP URL

Then click Save. The Composio server now appears in your MCP plugins list.

3. Authenticate

Click Authenticate on the Composio entry, log in via Composio, and click Allow access. Composio tools are then available in ChatGPT the same way as with the plugin.

What you can do after connecting OData

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

Security + privacy notes (important)

  • Use least-privilege access: Only grant permissions you actually need.
  • Review OAuth permissions before approving: Make sure requested scopes match what you expect Composio and ChatGPT to do.
  • Keep write actions human-reviewed: For actions like sending messages, creating labels, or editing drafts, keep manual confirmation enabled.
  • Be careful with sensitive data: Avoid using this setup with highly sensitive information unless allowed by your personal, company, or client policies.
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. ChatGPT 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.
