We couldn’t confirm it starts correctly
We ran the install command but it didn't respond within our test window — this can mean a slow first-time install rather than a real problem.
npx -y @ibm/ibmi-mcp-server@latestNo response to initialize.
This is an experimental automated check and can have false negatives — missing environment variables, a slow cold install, etc. It doesn’t necessarily mean something’s wrong. Last checked Today.

Frequently Asked Questions about Ibmi MCP Server
@ibm/ibmi-mcp-server is an MCP server that connects AI agents to IBM i systems through Mapepire and Db2 for i. Its main tools are YAML-defined SQL operations, including database queries, system information access, and performance monitoring such as system status, memory pools, and active jobs.
Install or run it with Node.js 18 or newer using npx, then provide a transport and YAML tool file. Configure the IBM i connection with DB2i_HOST, DB2i_USER, DB2i_PASS, DB2i_PORT, and DB2i_IGNORE_UNAUTHORIZED. Docker images are also provided for container deployment.
The documented connection variables are DB2i_HOST, DB2i_USER, DB2i_PASS, DB2i_PORT, and DB2i_IGNORE_UNAUTHORIZED. They identify the IBM i endpoint, credentials, Mapepire port, and whether unauthorized certificates should be ignored.
The provided material does not specifically document Cursor configuration. It describes MCP client connections and names Claude, VSCode Copilot, Bob, custom agents, Agno, and LangChain, so Cursor compatibility should be verified against its MCP transport and configuration support.
