Häufige Fragen

Ist Mainframe MCP Server sicher?

Er hat 1 von 1 zutreffenden Basischecks bestanden. Den Code haben wir nicht gelesen. Bevor du einen Schlüssel oder Token hinzufügst, sieh nach, welche Zugriffe der Server verlangt, und nutze einen Schlüssel, der nur die Berechtigungen hat, die du brauchst.

Welche Schlüssel oder Codes braucht er?

Das musst du eintragen: ZOSMF_HOST, ZOSMF_PASSWORD, ZOSMF_TOKEN

Läuft er auf meinem Computer oder in der Cloud?

Er läuft auf deinem Computer. Deine KI-App startet ihn bei Bedarf, und die Daten laufen nicht über die Server des Entwicklers (außer der Server ruft selbst einen Onlinedienst auf).

Wird er noch gepflegt?

Das GitHub-Repo wurde zuletzt – geändert, und die neueste Version (3.0.0) kam vor 12 Tagen in die Registry.

Welche Apps können ihn nutzen?

Apps, die MCP unterstützen, etwa Claude Desktop, Claude Code, Cursor und VS Code. Außerdem brauchst du Node.js auf deinem Computer.

Was kann ich stattdessen nutzen?

In derselben Kategorie: Spec Driven Development, Remote Desktop Commander, Zoo MCP

mainframe-mcp-server

MCP Server for IBM z/OS using Zowe APIs

An enterprise-grade Model Context Protocol (MCP) server for IBM z/OS environments.

Bridges MCP-compatible AI agents with mainframe resources — jobs, datasets, USS, and operational diagnostics — using the Zowe SDK (Open Mainframe Project) as the connectivity layer.

What it does

mainframe-mcp-server exposes z/OS capabilities as Model Context Protocol tools. An AI agent can list jobs, read datasets, inspect USS paths, submit JCL, and run operational diagnostics — without you writing Zowe CLI commands by hand.

Connectivity is handled by the Zowe SDK (Open Mainframe Project) over z/OSMF REST. This project adds the MCP tool layer, input validation, safety limits, and AI-friendly response formatting on top.

How it's different

	mainframe-mcp-server	Zowe CLI + scripts	Host IDE tooling (IDz, Z Open Editor)	Other z/OS MCP bridges
Interface	MCP tools for AI agents	Terminal commands, shell scripts	Eclipse/VS Code GUIs	MCP tools for AI agents
Output	Structured sections & tables tuned for LLM reasoning	Raw terminal text you must parse yourself	IDE views	Varies by project
Guardrails	Read-only by default, tool allow/block lists, dataset & USS boundaries, audit logging, JCL size cap	None built in — you script them	Client-side only	Varies by project
Failure knowledge	Curated abend-code reference, failing-step heuristics, risk scoring	Manual message lookup	Interactive debugging	Rare
Install	`npx` — no server-side footprint beyond z/OSMF access	Node + Zowe CLI + your scripts	Full IDE estate	Often heavier runtimes
Coverage	Jobs, datasets, USS, CICS, Db2, SMF/RMF, RACF audit (30+ tools)	Full Zowe command set	Edit, debug, compile	Varies

Honest positioning: the z/OS MCP ecosystem is early. IBM and community authors publish their own MCP bridges — evaluate them against your requirements. This project's differentiators are zero-dependency npm install, guardrails enforced at the server layer, and output shaped for LLM consumption rather than human eyes. It is not a replacement for Zowe CLI or IBM Z Open Editor — it is an MCP bridge over the same z/OSMF APIs.

z/OS prerequisites

The server is a pure client — nothing is installed on z/OS. It requires REST services that are enabled in standard z/OSMF estates.

z/OSMF (required — all core tools)

z/OSMF REST service	Used by	Notes
Jobs REST (`/zosmf/restjobs/jobs`)	`list_jobs`, `get_job_status`, `get_job_output`, `get_job_jcl`, `submit_jcl`, all operations & intelligence tools	List, query, spool content, JES submit
Files REST — datasets (`/zosmf/restfiles/ds`)	`list_datasets`, `search_dataset`, `read_dataset`, `search_members`, `get_dataset_info`	Catalog list, members, content read
Files REST — USS (`/zosmf/restfiles/fs`)	`list_uss_directory`, `read_uss_file`, `search_uss_files`, RACF audit source	Directory list, file read
z/OSMF info (`/info`)	`verify_zosmf_connection`	Optional; version read-out only
RMF REST (`/rmf/mvs/GPO/`)	`get_smf_metrics`	Optional; disabled with `RMF_METRICS_ENABLED=false`

Baseline: z/OS 2.4 LTS or later with APAR-current z/OSMF — the target the Zowe SDK (v8) is built against. Core job/dataset/USS tools are expected to work on z/OSMF levels from z/OS 2.3 onward; if you run an older or unusual level, open an issue with your results so the matrix can be updated.

CICS via CMCI (optional — `list_cics_regions`, `get_cics_region_status`, `list_cics_transactions`)

CICS TS 5.4 or later with CMCI active (a CICSPlex SM WUI region, or a single-region CMCI setup).
Set CMCI_CONTEXT (CICSplex name or region APPLID); optionally CMCI_HOST, CMCI_PORT (default 1490), CMCI_BASE_PATH (default /CICSSystemManagement).
The service account needs RACF/SAF authority to the CMCI data sets (XCSDATA/CICSPLEX resource classes as configured at your site).

Db2 REST (optional — `list_db2_subsystems`, `search_db2_catalog`)

Db2 12 for z/OS or later with the Db2 REST services capability exposed at DB2_HOST:DB2_PORT (default 50400, base path /dbrest) — direct DDF-served REST or fronted by your API mediation layer.
Set DB2_LOCATION (the subsystem location name). Tools run read-only catalog SQL against SYSIBM.SYSTABLES with literal-escaped, size-capped input.

RACF audit source (optional — `query_racf_audit`)

An existing audit extract the service account can read: a USS log file (RACF_AUDIT_USS_PATH) or a sequential dataset (RACF_AUDIT_DATASET), e.g. ADUINFOS/IRRADU00 output written to file. The server parses the text; it does not run IRRADU00 for you.

Service account

Use a dedicated z/OS user with least-privilege RACF profiles (job list/read authority, submit authority only if SECURITY_READ_ONLY=false).

Tools

Type legend: READ — reads z/OS state, never modifies anything · WRITE — submits work to JES · OFFLINE — no mainframe I/O at all.

`get_job_status`	READ	Status and return code for a job
`get_job_output`	READ	Spool inventory or DD content
`submit_jcl`	WRITE	Submit inline JCL — governed by pre-flight scan, change ticket, change window, and optional human approval
`approve_write`	WRITE	Execute a pending JCL submission after human review (requires `SECURITY_WRITE_APPROVAL=true`)
`analyze_job_failure`	READ	Abend code, failing step, and suggested fix
`get_job_jcl`	READ	Retrieve submitted JCL from job spool

Datasets

Tool	Type	Description
`list_datasets`	READ	List datasets matching an HLQ pattern
`read_dataset`	READ	Read a sequential dataset or PDS member
`search_dataset`	READ	Search datasets by pattern
`search_members`	READ	Search or list PDS members
`get_dataset_info`	READ	Catalog attributes without reading content

USS

Tool	Type	Description
`list_uss_directory`	READ	List a USS directory
`read_uss_file`	READ	Read a USS file
`search_uss_files`	READ	Search files under a USS path

Operations

Tool	Type	Description

`summarize_abends`	READ	Abend code breakdown across recent jobs
`system_health_summary`	READ	Active, queued, and failed job snapshot
`investigate_incident`	READ	Full incident bundle for a job
`lookup_abend_code`	OFFLINE	Abend reference lookup (S0C7, S806, S222, S0C4, …)
`verify_zosmf_connection`	READ	Test z/OSMF connectivity and auth
`compare_jobs`	READ	Side-by-side comparison of two jobs
`get_user_jobs_summary`	READ	Job counts by status for an owner

CICS

Requires optional CMCI configuration — see z/OS prerequisites.

Tool	Type	Description
`list_cics_regions`	READ	List CICS regions via CMCI REST
`get_cics_region_status`	READ	Status and attributes of a CICS region
`list_cics_transactions`	READ	Transaction definitions in a region
`get_cics_region_stats`	READ	Region statistics/attributes from the CMCI `CICSRegion` resource
`cics_newcopy`	WRITE	NEWCOPY a program via CMCI action (CICS TS 5.6+)

Tool	Type	Description
`list_db2_subsystems`	READ	List Db2 locations via Db2 REST
`search_db2_catalog`	READ	Read-only catalog search (tables, views, aliases)

Console & JES

Operator commands run through an extended MCS console (ZOSMF_CONSOLE_NAME); command tools are gated writes subject to read-only mode, policy roles, change tickets, and change windows.

Tool	Type	Description
`issue_console_command`	WRITE	MVS commands (`D A,L`, `D GRS,RES=…`) with follow-up message collection
