How to use Claude with the Arenza MCP server (Claude Desktop + Claude Code)

Arenza ships a hosted MCP server at mcp.arenza.ai that exposes 4 read-only tools (list_brands, get_brand_overview, list_prompts, list_opportunities). Add the server to Claude Desktop or Claude Code in 2 minutes; Claude can then answer "which of my client brands lost visibility this week?" in natural language without leaving the chat.

Model Context Protocol (MCP) is Anthropic's open standard for connecting language models to external tools. Arenza exposes its read-only data layer as an MCP server so Claude (Desktop, Code, or any MCP-aware client) can query brand AI visibility data directly.

What the Arenza MCP server can do

  • list_brands — return all brands the authenticated user owns, with visibility score and trend.
  • get_brand_overview(slug) — return AVS, wrong-claim count, top-cited domains for a brand.
  • list_prompts(brand) — return tracked prompts with last-run rank/mentions/citations.
  • list_opportunities(brand) — return active discussions + articles to write.

Write tools (add a competitor, schedule a digest, mark an opportunity done) ship in the next sprint.

Setup for Claude Desktop

  1. Open Claude Desktop → Settings → Developer → Edit Config.
  2. Add the Arenza MCP server entry to mcpServers (see config below).
  3. Restart Claude Desktop.
  4. In a new chat, type "list my brands" — Claude will call list_brands and render the result.
{
  "mcpServers": {
    "arenza": {
      "url": "https://mcp.arenza.ai/rpc",
      "headers": {
        "x-api-key": "<your Arenza API key — get from /settings>"
      }
    }
  }
}

Setup for Claude Code (CLI)

Claude Code's CLI accepts MCP servers via the same config schema. Edit ~/.claude/mcp.json:

{
  "arenza": {
    "url": "https://mcp.arenza.ai/rpc",
    "headers": { "x-api-key": "<your-api-key>" }
  }
}

Sample queries Claude can answer once connected

  • "Which of my client brands lost the most visibility this week?"
  • "Show me the top 5 cited domains for Acme Corp."
  • "What are the open opportunities for Globex right now?"
  • "Which prompts has Acme been mentioned in across ChatGPT and Claude?"

Why MCP-native matters for agencies

Most GEO tools ship a dashboard-only experience. That's fine if your team has 1 brand to look after. If you have 20, you don't want to context-switch between tabs — you want to ask Claude "summarize all client brands' AI visibility for the Monday standup" and have it done in one prompt. MCP makes that possible.

Roadmap

  • Q3 2026: write tools (mark opportunity done, schedule digest, add competitor) — gated behind OAuth-DCR.
  • Q3 2026: streaming (subscribe to alerts as MCP events).
  • Q4 2026: ChatGPT plugin parity (same tool surface).
