MentionFox in your AI tools

What you can do — 9 tools, one connection

Each tool runs server-side on MentionFox infrastructure. Your AI agent calls them, each paid call draws on your plan's monthly credits, and results land back in the conversation. Two of the nine are free. Current plans and credits are on the pricing page.

Setup in 60 seconds

Pick your AI client. Three steps, one connection, nine tools. No new account — your existing MentionFox login is the credential.

Pricing — credit-based, no surprises

Same MentionFox account, same subscription. There is no separate MCP plan: tool calls draw on the same monthly credits as the dashboard.

Most tools need Pro or above. save_to_my_pipeline and get_my_recent_research are free on every plan. See current plans and pricing →

Authentication & verification

MentionFox MCP uses OAuth. There is no API key to copy, paste, or rotate. The first time your AI client calls a MentionFox tool, you'll get a browser sign-in popup — once approved, the token persists for the client and you never see auth again unless you sign out.

What happens on first tool call

1. Your AI client (Claude / Cursor / Windsurf / Continue) detects a MentionFox tool was invoked.
2. It opens a browser tab pointed at https://mentionfox.com/auth?source=mcp.
3. You sign in with the same email you use on the MentionFox dashboard.
4. You'll see a one-screen approval: "Allow [your AI client] to call MentionFox tools on your behalf." Click Approve.
5. The browser tab closes itself and the tool call resumes inside your AI conversation.

Subsequent tool calls in the same client are seamless — no popups, no re-auth. The OAuth token lives in the client (Claude Desktop, Cursor settings, etc.), not in your code or your shell.

No new account needed

If you already have a MentionFox account, MCP uses that login. If you don't, the OAuth popup includes a "create account" link — you start on the Free plan and can upgrade from the pricing page.

Verify the connection works

After OAuth approval, drop this exact prompt into your AI client:

Use MentionFox to tell me about Sam Altman in one paragraph.

You should see your AI client decide to call get_dossier, then return a paragraph summary. The first tool call typically takes 8-15 seconds while the dossier is built. If you see the call in your client's tool-use UI but no response, see Troubleshooting below.

Troubleshooting

OAuth popup didn't open. Your client may be blocking popups. Check the client's tool-call log — most clients surface the OAuth URL there as a clickable link. Open it in any browser, sign in, approve. The client picks up the token automatically.

"Subscription required" error on every call. Your trial expired or your subscription lapsed. Open /dashboard/billing to reactivate. Tool calls return a 402 with the same message — your AI client will surface it as a tool error.

"Rate limit exceeded" / 429. You're calling more than 30 tools per minute. Wait a minute and retry — most clients retry automatically.

"Insufficient credits". You're past your monthly credit pool. Either wait until next month's reset or upgrade. The error message includes which tool you tried and how many credits short you were.

Tools list is empty after connecting. The OAuth flow completed but the client's MCP layer didn't refresh its tool list. In Claude: Settings → Connectors → MentionFox → Refresh. In Cursor / Continue: restart the client. The full 9-tool list should appear within seconds.

Audit your tool calls. Every MCP call you make lands in your MentionFox dashboard under Settings → MCP Activity with tool name, timestamp, arguments, credits charged, and success/failure. If a tool call seems to misfire, that's the canonical log to check.
