mcp-server-db2i

An open-source Model Context Protocol server enabling AI assistants to perform read-only SQL queries and schema inspection on IBM Db2 for i. It supports ODBC, JT400 JDBC, and Mapepire over SSH drivers, enforces read-only access via SQL validation, and provides library allowlists, column masking, and OAuth 2.1 authentication for secure, audited access without installing software on the IBM i system.
