qlik-sense-mcp-server 1.5.0

MCP Server for Qlik Sense Enterprise APIs

Qlik Sense MCP Server

Model Context Protocol server for Qlik Sense Enterprise. Exposes Qlik's Repository (HTTP) and Engine (WebSocket) APIs as 24 MCP tools so an LLM client can discover apps, inspect data models, build hypercubes, and manage reload tasks through a single uniform interface.

What's in the box

Area	Tools	Used for
Repository (apps & metadata)	get_about, get_apps, get_app_details	Discover apps, list tables and fields with cardinalities
Engine (data & script)	get_app_script, get_app_variables, get_app_sheets, get_app_sheet_objects, get_app_object, get_app_field, engine_get_field_range, get_app_field_statistics, engine_create_hypercube	Read load script, list visualizations, query field values, build hypercubes
Reload tasks	get_tasks, get_task_details, get_task_dependencies, get_task_schedule, get_task_executions, get_task_script_log, get_failed_tasks_with_logs, start_task, create_task, update_task, delete_task, create_task_schedule	Inspect, trigger and manage reload tasks

Quick start

uvx qlik-sense-mcp-server

The server starts in Streamable HTTP mode on http://127.0.0.1:8000/mcp. Configure it via environment variables — see docs/configuration.md.

For stdio mode (legacy MCP transport), pass --stdio.

Key facts about the v1.4.0 line

• Cached Engine WebSocket connections. Once an app is opened, every subsequent tool call against the same app_id reuses the same WebSocket and the same open document. Switching app_id closes the old document and opens the new one on the same socket. Dropped connections are reopened transparently. Implementation: engine_api.py and docs/architecture.md.
• Streamable HTTP transport by default. The server is a long-lived process; multiple MCP clients can talk to it in parallel. The legacy stdio mode still works behind --stdio.
• tool_call_seconds is injected as the first key of every tool response — wall-clock time of the call in milliseconds. Use it to spot slow tools.
• Hard hypercube limits. engine_create_hypercube rejects requests with max_rows > 5000 or columns * max_rows > 9900 immediately, with a structured error and a hint pointing at set-analysis or top-N patterns. Qlik Engine itself returns error 7009 calc-pages-too-large for any single page over 10000 cells.
• Single timeout knob. QLIK_WS_TIMEOUT (default 180.0 seconds) controls both the WebSocket handshake and every Engine API call.

Requirements

• Python 3.12 (the package is built and tested against this version; see pyproject.toml)
• Qlik Sense Enterprise (Repository on port 4242, Engine on port 4747 — the standard ports)
• Client certificate, private key and root CA from the Qlik Sense node
• Network access from the host running this server to Qlik
