ABAP_CHECK_MCP

The Python server itself has good security practices (e.g., sensitive data filtering in logs) and no direct 'eval' or malicious patterns. The primary security risk lies with the required SAP backend setup. The deployed ABAP function module `Z_CHECK_ABAP_SYNTAX` dynamically creates and deletes temporary ABAP programs (`INSERT REPORT`, `SYNTAX-CHECK FOR`, `DELETE REPORT`) on the SAP system based on user-provided ABAP code. This requires granting the RFC user highly privileged SAP authorizations (`S_PROGRAM` for create/delete programs). While these temporary programs are intended for syntax checking and are deleted, allowing arbitrary code to be inserted and processed, even temporarily, presents a significant attack surface if the input ABAP code is not from a trusted source or if the SAP system's handling of `INSERT REPORT` or `SYNTAX-CHECK` could be exploited. The Python server does not perform content-based sanitization of the ABAP code before sending it to SAP.
