Run your cold outreach from Claude — or any AI.
ProspectFlow ships a Model Context Protocol server. Connect it to your AI assistant with an API key and just ask: it finds prospects, drafts campaigns, and launches sends — all inside your workspace, with your deliverability rules intact.
You say
“Find 25 fintech founders in London, add them, draft a warm intro campaign, and schedule it for Tuesday 9am.”
Your AI calls find_prospects → add_prospects → create_campaign → launch_campaign. You approve the send.
Connect in three steps
Create an API key
In ProspectFlow, open AI / MCP in the dashboard and create an API key. It's shown once — copy it into your password manager.
Connect the MCP server
On claude.ai, add a custom connector with the URL https://prospectflow.business/api/mcp/pf_live_YOUR_KEY — your key travels in the URL, so no extra authentication is needed. Header-capable clients (mcp-remote, Cursor) keep https://prospectflow.business/api/mcp with the key as a Bearer token. The URL contains your key — treat it like a password and revoke it if it leaks.
Ask your AI to run outreach
Tell Claude what you want — “find 25 SaaS founders in Berlin and draft a campaign”. It calls the tools; you review and approve the send.
What the AI can do
A focused set of tools covers the whole loop — discovery to send — and nothing beyond it.
find_prospects
AI web search for new prospects matching an ICP you describe in plain English.
add_prospects / list_prospects
Add contacts (deduplicated) or browse the ones already in your workspace.
create_campaign
Draft a campaign with a subject and body — created as a draft, never sent.
add_prospects_to_campaign
Attach recipients to a campaign without sending anything.
launch_campaign
Send (or schedule) the campaign through your own SMTP, with deliverability protection.
get_analytics
Pull recipients, sends, opens, clicks and derived rates across your campaigns.
Server & config
claude.ai custom connector — paste this URL, with your API key as the last path segment (no extra auth):
https://prospectflow.business/api/mcp/pf_live_YOUR_KEYThis URL contains your key — treat it like a password and revoke it if it leaks.
Header-capable clients keep the Bearer form; local clients bridge with mcp-remote:
{
"mcpServers": {
"prospectflow": {
"command": "npx",
"args": [
"-y", "mcp-remote", "https://prospectflow.business/api/mcp",
"--header", "Authorization: Bearer pf_live_your_key_here"
]
}
}
}Safe by design
- • Keys are workspace-scoped — the AI only ever touches your account.
- • Creating a campaign makes a draft; only launch_campaign sends.
- • SMTP passwords and your inbox are never exposed to the AI.
- • Revoke a key any time; the connection dies instantly.
- • Every send keeps ProspectFlow's pacing and one-click unsubscribe.
Frequently asked questions
What is MCP?
The Model Context Protocol (MCP) is an open standard that lets AI assistants securely call external tools. ProspectFlow ships an MCP server, so an MCP-capable AI can operate your outreach through well-defined tools instead of screen-scraping the app.
Which AI clients can connect?
Any MCP client. On claude.ai, add a custom connector and paste the URL with your API key in its path — https://prospectflow.business/api/mcp/pf_live_YOUR_KEY — with no extra authentication. Header-capable clients like Cursor and Windsurf, and local-only clients behind the mcp-remote bridge, use https://prospectflow.business/api/mcp with the key as a Bearer token. Either way, the key is a password: revoke it if it leaks.
Will the AI send emails without my approval?
No. Creating a campaign only produces a draft — nothing leaves your account. Sending happens exclusively through the explicit launch_campaign tool, so an assistant takes a deliberate, visible step (that you direct) before any email is delivered.
What can a connected AI access?
Only the ProspectFlow workspace tied to the API key, and only through the published tools: campaigns, prospects, SMTP identities (names only — never secrets), templates and analytics. It cannot read your inbox or your SMTP passwords.
How do I revoke access?
Revoke the API key from the AI / MCP page in your dashboard. The MCP server rejects it immediately, cutting off that connection without affecting your other keys.
Which plans include the MCP server?
Every plan, including Free. The MCP server drives the same features you already have; your plan's sending limits and deliverability protections apply exactly as they do in the app.
