This listing does not currently have a tool list to display. This does not mean the server has no tools; check its documentation for supported capabilities.
We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.
IBM Informix MCP Server by CData is a read-only Model Context Protocol (MCP) server that allows LLMs like Claude Desktop to query live IBM Informix data using natural language, powered by the CData JDBC Driver for IBM Informix.
Clone the repository, build with mvn clean install, install the CData JDBC Driver, license it, create a .prp file with the JDBC connection string, and configure Claude Desktop by adding the server to claude_desktop_config.json. Run the server with java -jar CDataMCP-jar-with-dependencies.jar <path-to>.prp.

Java (to run the JAR), the CData JDBC Driver for IBM Informix (licensed), and an AI client that supports MCP (e.g., Claude Desktop). No additional databases or services are required.
The data remains in the IBM Informix database. The server queries that data live through the CData JDBC Driver; it does not copy or cache data locally.
Authentication is configured within the JDBC connection string (e.g., OAuth, username/password) using the CData JDBC Driver’s Connection String utility. The driver handles the credentials.
Yes. The server uses `stdio` transport, so it can only run on the same machine as the AI client (e.g., Claude Desktop). It does not support remote or network-based connections.
