We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.
Trello MCP Server by CData is a read-only Model Context Protocol (MCP) server that allows large language models (such as Claude Desktop) to query live Trello data via natural language. It leverages the CData JDBC Driver for Trello to expose Trello data as relational SQL models.
Clone the repository, build with Maven (mvn clean install), download and install the CData JDBC Driver for Trello, license it, then create a .prp file with your JDBC connection string. Add the server to your Claude Desktop configuration (claude_desktop_config.json) and restart the client. The server runs via stdio and provides tools like {prefix}_get_tables, {prefix}_get_columns, and {prefix}_run_query.
stdio transport – runs on the same machine as the clientYes, this server is explicitly read-only. For full read, write, update, delete, and action capabilities, CData offers a separate free beta server.
You need Java (JDK or JRE), Maven for building, and the CData JDBC Driver for Trello (requires a license or trial key). The server runs on Windows, macOS, or Linux.
Your data remains in Trello. The server queries it live over the internet using OAuth authentication configured during setup.
It uses the JDBC connection string you provide in the `.prp` file, which includes OAuth credentials. The driver handles authentication and data retrieval.
The server uses `stdio` (standard input/output) transport, so it must run on the same machine as the MCP client (e.g., Claude Desktop).
