- AlicenseNot gradedqualityBmaintenanceEnables AI assistants to interact with a classic MVS 3.8j system running under Hercules through mvsMF's z/OSMF-compatible REST API. Supports dataset listing/reading, member access, job submission, and job status/file retrieval via MCP tools.MIT
- FlicenseNot gradedqualityCmaintenanceLets an MCP-compatible AI assistant browse z/OS datasets, read COBOL/JCL source members, and submit and monitor batch jobs by wrapping IBM's z/OSMF REST API. Ships with a mock mode that returns canned data for demos, and can be switched to live HTTPS calls against a real z/OSMF instance via environment variables.-

Scored across 55 tools
Most tools target distinct resources or actions, but the failure/diagnosis cluster is crowded: find_failed_jobs, analyze_job_failure, investigate_incident, analyze_root_cause, summarize_abends, system_health_summary, and predict_batch_failures can be hard to choose between without careful reading. Similar overlap exists between list_datasets and search_dataset, and between list_uss_directory and search_uss_files, though descriptions generally clarify intent.
The set is predominantly snake_case with a verb-first pattern such as get_job_status, list_jobs, read_dataset, and submit_jcl. There are readable deviations including resource-first or noun-first names like cics_newcopy, cics_disable_transaction, mq_queue_status, scheduler_job_status, system_health_summary, and whoami, but overall the convention is mostly predictable.
At 55 tools, the surface is very large and imposes a significant selection burden on an agent even for a broad mainframe operations domain. While many tools are purpose-specific, the count goes well beyond the well-scoped 3-15 range and includes many niche diagnostics that could be consolidated.
The server has broad read coverage across JES, datasets, USS, CICS, Db2, RACF, SMF, console, MQ, storage, scheduling, and capacity. However, lifecycle coverage is uneven: dataset and USS operations lack create/update/delete, Db2 has catalog search but no query execution, and CICS has disable but no enable, creating notable gaps for a full mainframe operations surface.
