    "blastengine-mailer": {
      "command": "node",
      "env": {
        "BLASTENGINE_USER_ID": "userid-of-blastengine",
        "BLASTENGINE_API_KEY": "apikey-of-blastengine"

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
