Sisense MCP Server

A Model Context Protocol (MCP) server that provides integration with Sisense analytics platform. This server enables LLMs to interact with Sisense data models and create charts programmatically.

Features

• Transport Support: Streamable HTTP/SSE (for HTTP-based clients like Claude Desktop)
• Three MCP Tools:
  • getDataSources: Retrieve Sisense data sources (or data models)
  • getDataSourceFields: List all available fields for a specific data source
  • buildChart: Build charts from natural language prompts
• Per-Session Authentication: Sisense credentials passed via URL parameters
• TypeScript: Full type safety and modern ESM support
• Lightweight: Pure Node.js HTTP server, no heavy frameworks
• Fast: Optimized for Bun runtime, also runs on Node.js

Prerequisites

• Bun >= 1.0.0 (recommended) or Node.js >= 18.0.0
• Sisense instance with API access
• Sisense API token

Installation

bun install

Usage

Start the server:

bun run dev

The server will display the connection URL:

Sisense MCP Server running on http://localhost:3000

Connect with:
  http://localhost:3000/mcp?sisenseUrl=<SISENSE_URL>&sisenseToken=<SISENSE_TOKEN>

Endpoints:
  Health: http://localhost:3000/health
  Screenshots: http://localhost:3000/screenshots/

Connecting from Claude Desktop

Configure Claude Desktop to connect using the full URL with your Sisense credentials:

http://localhost:3000/mcp?sisenseUrl=https://your-instance.sisense.com&sisenseToken=your-api-token

Or via ngrok/public URL:

https://your-ngrok-url.ngrok-free.app/mcp?sisenseUrl=https://your-instance.sisense.com&sisenseToken=your-api-token

Configuration

Parameter	Description
sisenseUrl	Full URL to your Sisense instance (e.g., https://instance.sisense.com)
sisenseToken	Sisense API authentication token
PORT	(Optional) Server port, defaults to 3000

The server automatically derives its public base URL from request headers, so it works correctly behind proxies like ngrok.

Development

# Run server in development mode with hot reload
bun run dev

# Build the project
bun run build

# Run tests
bun test

# Type checking
bun run type-check

# Lint
bun run lint

Security Considerations

⚠️ NEVER commit credentials to version control ⚠️ Use secret managers or vaults - NOT environment variables in production ⚠️ NEVER bind to 0.0.0.0 in production - use 127.0.0.1 or Unix socket ⚠️ NEVER connect to production Sisense - use dev/staging environments only ⚠️ Enable authentication - never run without auth ⚠️ Approve EVERY tool call - review all parameters before execution ⚠️ Create dedicated Sisense service account with minimum required permissions ⚠️ Rotate credentials regularly (every 90 days recommended)
