Sisense MCP Server

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
• MCP Apps: When used in MCP Apps–capable clients (e.g. Claude), buildChart exposes an interactive View that renders the chart in an iframe within the app.
• 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:3001

Connect with:
  http://localhost:3001/mcp?sisenseUrl=<SISENSE_URL>&sisenseToken=<SISENSE_TOKEN>

Endpoints:
  Health: http://localhost:3001/health
  Screenshots: http://localhost:3001/screenshots/

Connecting from Claude Desktop

Credentials can be provided via URL params or via env vars SISENSE_URL and SISENSE_TOKEN. If both are set, URL params take precedence.

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

http://localhost:3001/mcp?sisenseUrl=https://your-instance.sisense.com&sisenseToken=your-api-token

Or set SISENSE_URL and SISENSE_TOKEN in your environment and connect with:

http://localhost:3001/mcp

Or via ngrok/public URL:

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

Configuration

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

Optional feature-flag query parameters

These query params override the corresponding env vars on a per-connection basis. Accepted values: true, false, 1, 0 (case-insensitive).

Example URL with all three overrides:

http://localhost:3001/mcp?sisenseUrl=https://your-instance.sisense.com&sisenseToken=your-api-token&mcpAppEnabled=false&toolBuildQueryEnabled=true&toolBuildChartNarrativeEnabled=false

Development

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

# Build the project (View + server)
bun run build

# Build only the analytics View (dist/view.html)
bun run build:view

# 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)
