Icypeas

Find a work email by name + company domain/name, via Icypeas (icypeas.com). Part of the enrich-waterfall finder rotation (fleet #2860).

Part of Pipeworx — an MCP gateway connecting AI agents to 1743+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• icypeas_find_email(first_name?, last_name?, domain_or_company, _apiKey) — work email with Icypeas's own certainty label.

Auth

BYO only. Pass your Icypeas API key as _apiKey (header Authorization: Bearer <key>). Enable API access and grab the key from the API section of your icypeas.com dashboard. No platform key (D4).

Data sources

• https://app.icypeas.com/api/email-search — email search.

Verification notes (fleet #2860, 2026-10-08, no vendor key held) — READ BEFORE TRUSTING THE PARSE

• Icypeas's documented model is ASYNC: the vendor's own docs (https://api-doc.icypeas.com/find-emails/email-discovery/) describe /email-search as enqueuing a search, with an optional webhook fired "when it is done" — implying the bare enqueue response does not itself carry the email. We hold no Icypeas key, so we could not make a real search end to end to see the actual success shape, and an unauthenticated probe cannot get past the 401.
• What IS confirmed by edge probe: the endpoint is live, and both no Authorization header and Authorization: Bearer invalidkey123 return the identical HTTP 401 {"message":"The user does not exist","error":"UserNotFoundError","status":401, "code":"user_not_found_error"} — so the header name is right and a bad key surfaces honestly (as "no such user") rather than silently.
• The parser is defensive, not confirmed: it reads a results array at either the top level or under item.results and takes the first entry with a non-empty email. This is a best-effort shape inferred from Icypeas's Make/n8n no-code integrations (which present single-search results inline), NOT a field-by-field confirmed response. If this pack returns found: false on every call even with a valid key, the first thing to check is whether /email-search actually hands back an item._id that must be polled via a separate results endpoint — that would mean this pack needs a second poll step added, not that the person has no email. Flagging this explicitly rather than letting a parse gap read as a mundane "not found."
• Not verified (no key held): the exact success response shape; whether a poll step is required; the certainty field's possible values.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "icypeas": {
      "url": "https://gateway.pipeworx.io/icypeas/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/icypeas/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1743+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

This pack takes your own API key (_apiKey) — we don't front one for it, so there's no curl here that would run without it. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/icypeas_find_email. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "icypeas": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-icypeas"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-icypeas

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Icypeas data" })

The gateway picks the right tool and fills the arguments automatically.
