CDT Express MCP Server
Interact with climate metrics via Riskthinking.AI's CDT Express API in supported AI chat experiences.
This project contains:
- The core MCP server that can be used to interact with Riskthinking.AI's CDT Express API.
- Distributable MCPB extension for the Claude desktop app in releases.
MCPB Extension Installation
- Download and install the Claude app from https://claude.ai/download.
- Download the
cdt-express.mcpbfile from the releases page. - Open the Claude Desktop app, go to "Settings" -> "Extensions" -> "Advanced settings".
- Click on "Install Extension", select the downloaded
cdt-express.mcpbfile. - Click on "Install".
- When prompted, enter your CDT Express API key, which is available at https://velo.riskthinking.ai/cdt-express.
- Review and enable the extension, then close the preview.
- The extension will be installed and you can use it in the app.
- When using for the first time, you may see the following prompt requesting for permission to use the extension provided tools, click on "Allow once" or "Always allow". a. Alternatively, you can manually configure in "Settings" -> "Extensions", and configure the Tool permissions for this extension.
- To update a new version, simply follow the same steps to "Install Extension", and click on "Update".

Development
- [Optional] Use nvm to manage Node.js versions.
nvm useto use the version specified in.nvmrc.
- Install dependencies:
npm i - Build and package the extension:
npm run pack:dev. You should find thecdt-express.mcpbfile in the root directory.- This command is different from
npm run packin that it installs back the development dependencies after packaging.
- This command is different from
Release
- [Human] Bump and sync the version in
package.jsonandsrc/server.ts(constantSERVER_VERSION), without thevprefix (e.g.0.5.2instead ofv0.5.2.) - [Human] Create a new git tag with the new version, with the
vprefix (e.g.v0.5.2). Typically do this through a new GitHub Release https://github.com/RiskThinking/cdt-express-mcp/releases/new, which has the advantage of ensuring code integrity and avoid unexpected local commits/changes. - [CI/CD] The GitHub Actions workflow will be triggered, and the MCPB extension will be built and published to the MCP Registry.
- The version across the git tag and package.json are checked to ensure consistency.
MCP Registry server.json
The version, package[0].sha256, and package[0].identifier fields in server.json are automatically calculated and injected by the GitHub Actions workflow, therefore intentionally not kept in version control.
Please refer to https://github.com/modelcontextprotocol/registry for latest details on the MCP Registry and track potential changes to the process.
MCPB manifest.json
The version field in manifest.json is automatically synced with the version in package.json by the npm run sync-manifest command (invoked by npm run pack), therefore intentionally not kept in version control. If you intend to make any manifest.json changes other than version, you should make sure to commit the changes before running npm run pack as it would reset (by git checkout manifest.json) the whole file.
Please refer to https://github.com/modelcontextprotocol/mcpb/blob/main/MANIFEST.md for the latest MCPB manifest specification.
