qlik-mcp-server: Instructions file for Claude Code

CLAUDE.md

qlik-mcp-server CLAUDE.md is an instructions file for Claude Code from arthurfantaci/qlik-mcp-server. It costs 1,042 tokens per session, scanned A, original, MIT.

Repository-specific instructions for developing a Python server that connects to Qlik Sense applications through WebSockets. Qlik Sense is software for creating interactive data reports and dashboards.

In plain words
What is it for?
Use them to install dependencies, configure and run the server, inspect its components, and run unit or integration tests.
Why use it?
They document setup, architecture, test commands, and the difference between tests that need a live Qlik system and those that do not.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

qlik-mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

Model Context Protocol (MCP) server providing comprehensive access to Qlik Sense applications via WebSocket API. FastMCP-based implementation with 9 tools for extracting app metadata, expressions, scripts, and visualizations.

Commands

# Setup (UV recommended, requires Python 3.10+)
uv sync                               # Install dependencies and create venv
cp .env.example .env                  # Configure Qlik server details

# Run server
uv run python -m src.server           # Start MCP server

# Test with pytest
uv run pytest                           # Run all tests
uv run pytest -v                        # Verbose output
uv run pytest -m unit                   # Unit tests only (no Qlik needed)
uv run pytest -m integration            # Integration tests (requires Qlik)
uv run pytest --cov=src                 # With coverage report

# Debug WebSocket client
uv run python -m src.qlik_client

Architecture

Core Components

  • src/server.py - FastMCP server registration and tool handlers
  • src/tools.py - 9 tool implementations with Pydantic validation
  • src/qlik_client.py - WebSocket client for Qlik Engine API

Key Patterns

  • SSL certificate authentication via certs/ directory
  • WebSocket connection to Qlik Engine API
  • Session objects for metadata (measures, variables, fields, dimensions)
  • Handle-based access for sheets and visualizations
  • Pydantic models with FastMCP auto-schema generation
  • Enhanced script analysis with BINARY LOAD extraction and section parsing

Connection Flow

  1. Load SSL certificates → WebSocket connect
  2. App operations: OpenDoc → create session objects → GetLayout
  3. Global operations: connect to /app/ → GetDocList
  4. Sheets: GetAllInfos → GetObject → GetLayout
  5. Always disconnect to prevent resource leaks

Tool Patterns

Parameter Validation: All tools use Pydantic models with field constraints, custom validators, and auto-generated schemas for FastMCP.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
