Wire FoxAPIs into Claude Desktop in under 60 seconds.

Claude Desktop speaks Model Context Protocol natively. You drop the FoxAPIs endpoint into one config file, restart Claude, and every tool in the catalog becomes callable in plain language. No glue code. No npm install.

Step-by-step install

1. Open the Claude Desktop config file. macOS: ~/Library/Application Support/Claude/claude_desktop_config.json. Windows: %APPDATA%\Claude\claude_desktop_config.json.
2. Add a top-level mcpServers object if it isn't already there. Inside it, add a foxapis entry pointing at the live endpoint.
3. Paste your FoxAPIs API key into the headers block. (Get one at /pricing.)
4. Save the file and fully quit Claude Desktop. Reopen.
5. Click the tools icon in the chat composer. You should see foxapis listed with all tools enabled.

// claude_desktop_config.json
{
  "mcpServers": {
    "foxapis": {
      "transport": "http",
      "url": "https://www.mentionfox.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_FOXAPIS_KEY"
      }
    }
  }
}

Three worked examples

Example 1 — Vet a person before a meeting

Type into Claude:

Vet Marc Andreessen for me before our 4pm. Pull his last
12 months of public commentary and any risk markers.

Claude resolves the request to vet_person, fires the call, and lays out the result with citations.

Example 2 — Compare three vendors

Compare Datadog, Grafana Cloud, and New Relic on
open-source friendliness and total cost at 50 hosts.
Show me the matrix and the ranked list.

Claude calls compare_subjects with the three vendors and your criteria string.

Example 3 — Daily GEO check

What's my GEO score for resend.com today, and what are
the top 3 actions I can ship without engineering?

Two calls in one prompt: get_geo_score followed by get_geofixer_top_actions with max_difficulty=60.
