We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.
Google Contacts MCP Server by CData is a read-only Model Context Protocol (MCP) server that lets large language models (LLMs) like Claude Desktop query live Google Contacts data. It wraps the CData JDBC Driver for Google Contacts, which exposes contacts as relational SQL models, so users can ask natural language questions without writing SQL.
Clone the repository, build the JAR with mvn clean install, install and license the CData JDBC Driver for Google Contacts, configure a JDBC connection string using the driver’s utility, create a .prp file with driver path, class, JDBC URL, and prefix, then add the server to Claude Desktop’s claude_desktop_config.json using the Java command pointing to the JAR and .prp file. Once configured, ask the LLM questions about your contacts (e.g., “How many open tickets do I have?”) and it will use the available tools automatically.
get_tables, get_columns, run_query.This server is read-only; it only allows querying data. For full create, update, delete, and action capabilities, use the free [CData MCP Server for Google Contacts (beta)](https://www.cdata.com/download/download.aspx?sku=ECZK-V&type=beta).
Java (to run the JAR), Apache Maven (to build), and the CData JDBC Driver for Google Contacts (must be installed and licensed). The server uses stdio transport, so it must run on the same machine as the client.
Data remains in Google Contacts; the server queries it live via the JDBC driver. OAuth authentication is handled by the driver (use `InitiateOAuth=GETANDREFRESH` in the JDBC URL) and requires browser-based authorization during setup.
Three tools: `{prefix}_get_tables`, `{prefix}_get_columns`, and `{prefix}_run_query`. The prefix is set in the `.prp` configuration file.
It is read-only—no write, update, or delete operations. It uses stdio transport, so the client must run on the same machine as the server. The JDBC driver requires a license (trial or paid).
