CDT Express MCP

Explore climate hazards, physical assets, companies, and market climate risk with Riskthinking.AI data in your AI app.

Connect by URL (recommended)

Use the hosted Streamable HTTP server. You need a VELO account with CDT Express access.

https://mcp.riskthinking.ai/mcp

1. Add a custom MCP connection in your AI app. Name it CDT Express and paste the URL above. If asked for a transport, choose Streamable HTTP.

2. Connect with OAuth. Sign in to VELO and approve access. Keep automatic client registration or the client's published identity selected; leave manual client ID, client secret, and API key fields empty.

3. Enable CDT Express in your conversation and try a prompt below.

Where to add the connection:

Custom connections depend on your app and workspace permissions. A workspace administrator may need to add or allow the connection first. No local server installation or API key is needed for the remote connection.

Try it

• “Explain dcr_score and cvar_95 using the CDT Express metric glossary.”

• “Show extreme-heat exposure for Toronto at latitude 43.6532, longitude -79.3832, under ssp245 in 2050.”

• “Find Microsoft in CDT Express and retrieve its climate risk scores for ssp245 in 2050.”

The 40 read-only tools cover climate exposure and impact metrics, hazard distributions, assets, companies, and market indexes. Available data depends on your account permissions; API calls may consume your quota. Use narrower filters or ask for a small sample when exploring large datasets.

Local Claude Desktop extension (MCPB)

The MCPB runs the connector on your computer and uses your CDT Express API key. It still needs an internet connection to retrieve data.

1. Install Claude Desktop and download the latest cdt-express.mcpb.

2. Open Settings → Desktop app, select Manage next to Extensions, then Advanced settings → Install Extension and choose the file. Older Claude versions show Settings → Extensions → Advanced settings.

3. Enter your API key from VELO, finish installation, and enable the extension's tools in your conversation.

To update, install the newer MCPB and choose Update. See Claude's extension guide if the settings differ in your version.

Need help?

• Can't add a connection? Check that your app and workspace allow custom MCP servers. Use the setup guide for your client above.

• Sign-in expired or access stopped? Disconnect and reconnect to authorize again. For local MCPB, check the API key in the extension settings.

• Permission or quota error? Check your CDT Express access and usage in VELO.

• Large response or timeout? Narrow the filters or request fewer results.

Report an issue with your client, tool name, and error message. Remove API keys, tokens, authorization URLs, and private data before sharing. More detailed checks are in the client testing guide.

Tool inputs, such as coordinates and company searches, are sent to the CDT Express API; results return to your AI app. The connector does not request your whole conversation. Remote authorization uses VELO; the local extension uses the API key you configure in Claude. Your AI app and connected services apply their respective data-handling policies.
