Überblick

Beschreibung vom Entwickler (englisches Original)

MCP server for IBM z/OS jobs, datasets, USS, and operational diagnostics via Zowe SDK.

Die drei Säulen von PopNx MCP

Diese drei werden nie zu einer Punktzahl zusammengefasst: Meinungen, Messungen und Beliebtheit sind verschiedene Dinge.

Was du damit machen kannst

Für diesen Server haben wir noch keine Zusammenfassung in einfacher Sprache geschrieben. Unten stehen die Fakten, die wir aus der Registry gelesen haben.

  • Verbindung: Läuft auf deinem Computer
  • Transport: stdio
  • Kategorie: Datenbanken & Datensätze
  • Das musst du eintragen: ZOSMF_HOST, ZOSMF_PASSWORD, ZOSMF_TOKEN

Installation

Wähle die KI-App, die du nutzt, und kopiere die Einstellungen.

Bevor du installierst

  • Basischecks: 1 von 1 bestanden
  • Läuft auf deinem Computer mit den Rechten deines Benutzerkontos (Dateien, Netzwerk, Apps).
  • Das trägst du selbst ein: ZOSMF_HOST, ZOSMF_PORT, ZOSMF_BASE_PATH, ZOSMF_USER, ZOSMF_PASSWORD, ZOSMF_TOKEN, ZOSMF_TOKEN_TYPE, ZOSMF_REJECT_UNAUTHORIZED, ZOSMF_CERT, ZOSMF_CERT_KEY, ZOSMF_TOKEN_FILE, ZOSMF_USER_ID, ZOSMF_PASSTICKET_APP, ZOWE_TEAM_CONFIG, ZOSMF_PROFILE, LOG_LEVEL, MCP_TRANSPORT, MCP_SSE_PORT, MAX_JOB_OUTPUT_LINES, MAX_DATASET_READ_LINES, MAX_JES_SPOOL_FILES, MAX_AUDIT_LINES, CMCI_CONTEXT, CMCI_HOST, CMCI_PORT, CMCI_BASE_PATH, DB2_LOCATION, DB2_HOST, DB2_PORT, DB2_BASE_PATH, SMF_SUMMARY_DATASET, RMF_METRICS_ENABLED, RACF_AUDIT_USS_PATH, RACF_AUDIT_DATASET, SECURITY_READ_ONLY, SECURITY_ALLOWED_TOOLS, SECURITY_BLOCKED_TOOLS, SECURITY_ALLOWED_DATASET_PATTERNS, SECURITY_ALLOWED_USS_PATHS, SECURITY_AUDIT_LOGGING, SECURITY_MAX_JCL_BYTES, SECURITY_WRITE_APPROVAL, SECURITY_JCL_SCAN, SECURITY_JCL_SCAN_STRICT, SECURITY_BLOCKED_PROGRAMS, SECURITY_BLOCKED_JOB_CLASSES, SECURITY_CHANGE_TICKET_PATTERN, SECURITY_WRITE_WINDOW, SECURITY_WRITE_DAYS, SECURITY_WRITE_WINDOW_TZ

Als geheim markierte Werte sind Schlüssel zu deinem Konto. Gib sie nie weiter und füge sie nie in einen Chat ein.

Du brauchst

  • npmNode.js installiert (für den Befehl npx)

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 14 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: Supabase, MongoDB MCP Server, Elasticsearch MCP Server

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.

  • Prompts & resources (MCP-native surface)
  • Enterprise security

  • Per-user identity & SSO

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.

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 serviceUsed byNotes
Jobs REST (/zosmf/restjobs/jobs)list_jobs, get_job_status, get_job_output, get_job_jcl, submit_jcl, all operations & intelligence toolsList, query, spool content, JES submit
Files REST — datasets (/zosmf/restfiles/ds)list_datasets, search_dataset, read_dataset, search_members, get_dataset_infoCatalog list, members, content read
Files REST — USS (/zosmf/restfiles/fs)list_uss_directory, read_uss_file, search_uss_files, RACF audit sourceDirectory list, file read
z/OSMF info (/info)verify_zosmf_connectionOptional; version read-out only
RMF REST (/rmf/mvs/GPO/)get_smf_metricsOptional; 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.
