## Description
Query your favorite B2B data APIs through us. Same request, same price, no markup. Use it from Claude, ChatGPT or Cursor: add api.datacircle.dev/mcp as an MCP server. The first time, your client signs you in with your Datacircle email (OAuth). Or send your API key as a Bearer token.

## What Datacircle MCP server does

The Datacircle MCP server provides an MCP access point for querying B2B data APIs. Instead of connecting an AI client directly to each data provider, you configure the client to use Datacircle’s endpoint at `api.datacircle.dev/mcp`.

The service is intended for requests to supported B2B data APIs. The supplied information does not identify the specific providers, datasets, query operations, or response schemas available through the endpoint, so you should verify API coverage with Datacircle before depending on a particular data source.

Datacircle describes its pricing model as keeping the same request price without adding a markup. That pricing statement applies to requests made through its service; the available material does not specify plan limits, quotas, or billing setup.

## How it works

An MCP-compatible client connects to the Datacircle endpoint and sends data requests through the MCP interface. The client can be Claude, ChatGPT, or Cursor according to the provided description, although no client-specific setup details are supplied.

Authentication supports two paths. On the first connection, the client can start an OAuth sign-in flow using a Datacircle email address. Alternatively, you can authenticate by sending a Datacircle API key in the HTTP `Authorization` header as a Bearer token. The Datacircle MCP server therefore suits both interactive client sign-in and setups where a token is already available.

## Setup and configuration

Add this MCP server URL to the client’s MCP configuration:

```text
https://api.datacircle.dev/mcp
```

The provided description does not include a client-specific configuration file, command, package, or local installation method. It presents Datacircle as a remote MCP endpoint, so setup consists of registering the URL in a supported client and completing authentication.

For OAuth, allow the client to open the Datacircle sign-in flow and use the Datacircle email associated with the account. For token authentication, configure the client or request layer to send the API key as a Bearer token. Keep the key private and follow the client’s method for storing credentials.

## Tools and capabilities

The documented capability is querying B2B data APIs through MCP. The source material does not list individual MCP tool names or describe parameters, filters, pagination, structured outputs, or write operations. Treat the endpoint as read/query-oriented unless Datacircle’s current API documentation confirms additional operations.

The Datacircle MCP server can be a fit when an agent needs B2B data access inside an existing MCP client and you prefer one connection point. It is less suitable for evaluation based on a particular provider or operation until you confirm that Datacircle supports it.

## Limitations and notes

No README or detailed API reference was provided with this listing. As a result, the supported B2B APIs, tool catalog, request formats, response formats, rate limits, account requirements, and pricing details beyond the no-markup statement cannot be confirmed here.

ChatGPT is named as a usable client in the source description, but it is not represented in the supplied compatibility-slug list. OAuth behavior may also vary by client, so confirm that the client supports remote MCP authentication before configuring the endpoint.

The Datacircle MCP server is a remote service rather than a documented local package in the supplied material. No license information is available.
