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
- Open Claude Desktop → Settings → Developer → Edit Config.
- Add the Arenza MCP server entry to mcpServers (see config below).
- Restart Claude Desktop.
- 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).
