@fullmention/mcp-server

The FullMention MCP Server provides a secure, high-performance gateway that allows Large Language Models (LLMs) and AI agents (such as Claude Desktop, Cursor, or custom agent networks) to interact directly with the FullMention Public API.

By exposing FullMention’s stateless simulation runs as native MCP tools and structured resources, your AI models can trigger batch analysis runs, track progress, fetch results, and analyze visibility metrics seamlessly.

Quickstart: Connect your AI Client (Local Desktop)

To connect the FullMention MCP Server to your local editor or chat client, configure your client using the configurations below.

1. Claude Desktop Setup

Add the following configuration to your claude_desktop_config.json (typically located at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "fullmention": {
      "command": "npx",
      "args": ["-y", "@fullmention/mcp-server"],
      "env": {
        "FULLMENTION_API_KEY": "your_fm_live_key_here"
      }
    }
  }
}

2. Cursor Setup

1. Open Cursor Settings and go to Features -> MCP.

2. Click + Add New MCP Server.

3. Fill in the configuration:

   • Name: FullMention

   • Type: stdio

   • Command: npx -y @fullmention/mcp-server

4. Set the environment variable FULLMENTION_API_KEY to your API key.

5. Click Save.

Core Architecture & Smart Shielding

The FullMention MCP Server is designed from the ground up to be AI-safe and highly resource-efficient, shielding your API quotas and credit budgets automatically:

• 🛡️ In-Memory Query Shielding: Caches query responses (60-second TTL) to protect your external API rate limits from redundant agent loops.

• 🚦 Status Polling Guardrails: Detects rapid-succession polling of active batch-run statuses. If an AI agent polls the server within 8 seconds, the server intercepts the network call and returns cached state with a [POLLED_TOO_FAST_CACHED_WARNING], saving network overhead and API stress.

• 📊 Server-Side Share of Voice: Automates brand-visibility calculation server-side with get_share_of_voice to completely prevent mathematical hallucinations in LLMs.

• 🚀 Server-Side Token Optimization: Supports a format: "markdown" parameter. Instead of sending raw verbose JSON to the LLM, the MCP server automatically compiles your data into highly compressed, dense Markdown tables, saving massive token overhead and drastically reducing your LLM input cost.

Exponentiate with Cloud Deployment (SSE Mode)

For SaaS and cloud architectures, the FullMention MCP Server supports SSE (Server-Sent Events) HTTP Transport dynamically out of the box.

Launching in SSE Mode:

To spin up the HTTP gateway on port 3000 (or configured PORT / FULLMENTION_MCP_PORT):

npx -y @fullmention/mcp-server --sse

100% Secure Metrics Endpoint

When hosted in SSE mode, you can inspect diagnostics and live caching performance metrics via:

curl http://localhost:3000/diagnostics
