DemandSphere MCP Server

An MCP (Model Context Protocol) server that connects AI assistants to the DemandSphere search intelligence platform. Supports both traditional SERP analytics (v5.0) and GenAI visibility tracking (v5.1).

What It Does

This server exposes 20 tools across five domains:

Domain

Tools

API Version

Site Discovery

list_sites, list_sites_flat

v5.0

SERP Analytics

serp_analytics (views: performance, trends, engine_comparison, engine_summary), get_keyword_groups, get_local_rankings, get_landing_matches, get_landings_history

v5.0

GenAI Visibility

get_mentions, get_keyword_citations, get_bulk_citations, get_site_citations, llm_analytics (views: stats, performance, channels, cross_channel, cross_llms), get_llm_filters, get_people_also_ask

v5.1

Brand Management

list_brands, create_brand, update_brand, delete_brands

v5.1

Quick Start

1. Install

With uv (recommended):

git clone https://github.com/DemandSphereDev/demandsphere-mcp.git
cd demandsphere-mcp
uv sync

With pip:

git clone https://github.com/DemandSphereDev/demandsphere-mcp.git
cd demandsphere-mcp
python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
pip install -e .

2. Configure API Key

Choose one method:

# Option A: Environment variable
export DEMANDSPHERE_API_KEY="your-api-key"

# Option B: Config file
mkdir -p ~/.config/demandsphere
echo '{"api_key": "your-api-key"}' > ~/.config/demandsphere/config.json

# Option C: .env file in project root
echo 'DEMANDSPHERE_API_KEY=your-api-key' > .env

3. Run

With uv:

# stdio (default — for Claude Code, Claude Desktop, Cursor)
uv run demandsphere-mcp

# HTTP (for hosted/remote deployment)
DEMANDSPHERE_TRANSPORT=streamable-http uv run demandsphere-mcp

With pip (after install):

# stdio
demandsphere-mcp

# HTTP
DEMANDSPHERE_TRANSPORT=streamable-http demandsphere-mcp

4. Connect to Your MCP Client

Claude Desktop / Cursor — add to your MCP config:

With uv:

{
  "mcpServers": {
    "demandsphere": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/demandsphere-mcp", "demandsphere-mcp"],
      "env": {
        "DEMANDSPHERE_API_KEY": "your-api-key"
      }
    }
  }
}

With pip (after pip install -e .):

{
  "mcpServers": {
    "demandsphere": {
      "command": "demandsphere-mcp",
      "env": {
        "DEMANDSPHERE_API_KEY": "your-api-key"
      }
    }
  }
}

Claude Code:

claude mcp add demandsphere \
  -e DEMANDSPHERE_API_KEY=your-api-key \
  -- uv run --directory /path/to/demandsphere-mcp demandsphere-mcp

OS process isolation; no network exposure

HTTPS via reverse proxy

API Key Handling

The DemandSphere API uses query-parameter auth. The MCP server holds the key and injects it into every outbound request. The AI model never sees the key.

Important: Because the API key is in the URL query string, it may appear in reverse proxy access logs, CDN logs, or network monitoring tools. If deploying behind a reverse proxy, configure it to strip or redact query strings from access logs.

Environment variable

Local dev, CI/CD

Config file (~/.config/demandsphere/)

Personal machines

.env file

Local dev

Self-Hosting

You can deploy the MCP server yourself on any platform that supports Docker or Python:

Docker:

docker build -t demandsphere-mcp .
docker run -p 127.0.0.1:8765:8765 \
  -e DEMANDSPHERE_API_KEY=your-api-key \
  demandsphere-mcp

The server is available at http://localhost:8765/mcp. Works with Cloudflare Workers, Railway, Fly.io, Northflank, Render, Google Cloud Run, AWS Fargate, or any container platform. A docker-compose.yml is included with production hardening (cap_drop, read_only, non-root).

Without Docker:

DEMANDSPHERE_TRANSPORT=streamable-http \
DEMANDSPHERE_HOST=0.0.0.0 \
DEMANDSPHERE_API_KEY=your-api-key \
demandsphere-mcp

Put an HTTPS reverse proxy (Caddy, nginx, Cloudflare Tunnel) in front for production use.

Rate Limiting

Client-side token-bucket rate limiter (default: 60 req/min). Response shaping caps result sets at 100 rows per tool call to keep LLM token costs manageable. Both are configurable via environment variables.

Configuration Reference

All settings via environment variables (prefix DEMANDSPHERE_):
