Api Key

Cdr platform is an API for purchasing carbon dioxide removal services. It enables businesses to offset emissions by accessing verified carbon removal projects.

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 Cdr platform account to Claude via Composio Connect, enabling it to estimate cost for removing 10 tons CO2, check CDR platform service status now, show current billing thresholds and fees, 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 Cdr platform 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 Cdr platform account

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

For example, ask Claude to:

  • "Estimate cost for removing 10 tons CO2"
  • "Check CDR platform service status now"
  • "Show current billing thresholds and fees"

It will prompt you to authenticate and authorize access.

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

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

The Cdr platform MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Cdr platform account. It provides structured and secure access to your carbon removal services, so your agent can estimate CDR costs, check platform health, retrieve billing info, and even purchase carbon credits on your behalf.

  • Instant CDR price estimation: Ask your agent to calculate the cost of carbon dioxide removal based on selected methods and quantities before making a purchase.
  • Service health monitoring: Let your agent verify the operational status of the Cdr platform, including API and database connectivity, to ensure everything is running smoothly.
  • Up-to-date billing and pricing info: Retrieve current pricing, fees, and billing thresholds for carbon removal services to inform purchasing decisions and budget planning.
  • Automated carbon removal purchases: Empower your agent to initiate and complete purchases of carbon dioxide removal credits after confirming costs and selected methods.

Troubleshooting

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

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

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

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

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

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

3. Why does the Cdr platform authorization link not work?

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

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

4. Why do Cdr platform actions fail after they worked before?

The Cdr platform connection can expire or lose permission.

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

5. How do I switch to a different Cdr platform account?

Claude can manage the Cdr platform connection for you.

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

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

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

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

FAQ

Frequently asked questions

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

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