FAQ from SendGrid MCP Server by CData

What is the difference between this server and the CData MCP Server for SendGrid (beta)?

This server is read‑only and requires building the JAR and manual driver setup. The beta server offers full read, write, update, delete, and action capabilities with a simpler setup.

What are the prerequisites to run this server?

You need Java, Maven, the CData JDBC Driver for SendGrid (downloaded and licensed), and the property file with your JDBC connection string.

How do I configure the connection to SendGrid?

Use the JDBC Connection String utility (run java -jar cdata.jdbc.sendgrid.jar) to test and copy the connection string, then place it in the .prp file under JdbcUrl. The driver handles OAuth authentication when needed.

What transport does the server use?

The server uses stdio transport, so it can only be used with clients running on the same machine as the server.

Is this server read‑only?

Yes. The README explicitly states it builds a read‑only MCP server. For full CRUD, refer to the separate CData MCP Server for SendGrid (beta).
