Native research, monitoring, and outreach inside Claude, Cursor, ChatGPT, Windsurf, and any AI agent that speaks MCP. Nine tools. Sixty-second setup. Same MentionFox subscription, no extra account.
Each tool runs server-side on MentionFox infrastructure. Your AI agent calls them; you pay credits per call; results land back in the conversation. Two of the nine are free — the others are credit-priced for fairness, with hard caps to prevent surprise bills.
OSINT-driven background on anyone — recent activity, contact hints, key signals, reputation, what they're publicly working on right now.
Logo, positioning, tech stack hints, recent news. Useful for cold-outreach prep, vendor evaluation, and competitive context.
Deep OSINT report on a VC or angel — fund history, thesis, recent deals, red flags, contact info. Built for founders mid-fundraise.
Full background on a founder — past startups, exit history, public reputation, red flags. Built for investors evaluating cap-table additions.
Verified email, phone, LinkedIn, social profiles, basic background. The fast lane when you already have a name and need a way to reach them.
Up to 20 journalists who recently wrote about a beat, with publication, recent bylines, and contact hints. Built for PR pitches and source-finding.
50+ platforms scanned for mentions of a topic, brand, or person in the last 24 hours. Returns up to 50 mentions with source, sentiment, found-at.
Push a researched lead into your MentionFox CRM as a new pipeline entry. Append-only — never modifies or deletes existing leads.
List your recent person dossiers and research output. Lets your AI agent reference what you've already looked up without redoing the work.
Pick your AI client. Three steps, one connection, nine tools. No new account — your existing MentionFox login is the credential.
https://www.mentionfox.com/mcpAfter connection, ask Claude any of the prompts above. The tool calls happen invisibly; results stream back into the conversation.

Cursor will open a browser tab for OAuth. Sign in to MentionFox once. Tools then surface in any Cursor agent chat.

For agents using the Anthropic SDK / OpenAI SDK directly: add the MCP URL to your tool registry, the SDK handles auth. Full docs at help/mcp.
Some clients (like the n8n community node) need a bearer token you paste, not an in-client OAuth popup. Generate one from your dashboard, then paste it into the client's credential.

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.
https://www.mentionfox.com/auth?source=mcp.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.
If you already have a MentionFox account, MCP uses that login. If you don't, the OAuth popup includes a "create account" link — same 7-day free trial, same 500 credit grant, no card required.
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 (the dossier synthesis runs Sonnet under the hood). If you see the call in your client's tool-use UI but no response, see Troubleshooting below.
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.

Model Context Protocol is an open standard for connecting AI tools (Claude, Cursor, ChatGPT, Windsurf, custom agents) to external services. The AI agent gets a list of tools it can call; when it needs one, it sends a structured request, the service runs, the result comes back into the conversation. MentionFox exposes 9 of its endpoints over MCP so any AI tool can use them natively.
Three reasons. First, the dashboard requires you to context-switch — open MentionFox, search, copy result, paste back. MCP keeps you in your AI tool. Second, AI agents can chain tools — research, enrich, save to pipeline, draft outreach — without you orchestrating. Third, AI agents make better use of structured tool output than humans skimming a UI: they parse the full payload and reason about it.
Yes. There's no separate MCP plan. Starter / Growth / Scale all include MCP at the credit caps shown above. The 7-day trial includes MCP too — 500 calls, no card required.
Each plan grants a monthly credit pool. Tool calls deduct from the pool at the per-tool cost shown above. When the pool runs out, calls return a 402 error with a clear upgrade path; no surprise overage charges. Tier-1 tools also share a separate per-month call cap — once you hit it, those four tools hard-block until the next month or until you upgrade.
Yes. The MCP endpoint is rate-limited at 30 calls/minute per user (per tier) and tool calls have a 25-second wall — both designed for production agent traffic. For higher volumes or custom contracts above the standard caps, hit support; we'll set up a Scale-plus arrangement.
The data MentionFox returns is OSINT — public-only sources, no scraping behind logins, no data brokers selling private records. Calls you make are logged for billing and tier-cap enforcement (tool name, timestamp, success / failure, credits charged). Tool inputs are not used to train any model. Full privacy details at /privacy.
30 calls per minute per user (across all tools combined). Per-month tier caps are enforced separately (see pricing table). No burst limits, no throttling on free tools (save_to_my_pipeline, get_my_recent_research). If you hit the per-minute limit, calls return 429 with a clear retry-after; just wait and retry.
You keep MCP access through the end of the billing period. After that, the connection stays — but tool calls return a clear "subscription required" error until you reactivate. Your saved pipeline data, dossiers, and research history are preserved for 90 days post-cancellation.
Yes. Every MCP tool call shows up in your MentionFox dashboard under Settings → MCP Activity — tool name, timestamp, arguments, credits charged, success/failure. Build trust between you and your AI agent by auditing the trail.
Anything that speaks MCP over HTTP. Confirmed working: Claude (web + desktop), Cursor IDE, Windsurf, Continue.dev, ChatGPT custom GPTs (via MCP gateway), Anthropic SDK + OpenAI SDK direct integrations. If your client speaks the open MCP spec, MentionFox works.
