About

Dropcontact ships in the w6w first-party pack. It declares 7 actions, 3 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview

Dropcontact finds and verifies business email addresses and enriches B2B contacts and companies: civility, qualified emails (nominative, generic, catch-all), phone, job level and function, company website, LinkedIn, SIREN/SIRET, VAT, NAF code, headcount and turnover.

Enrichment is asynchronous. A workflow submits up to 250 contacts as one batch and gets a request id back, then either polls for the result (Dropcontact asks for roughly 30 seconds between polls), asks for whatever is ready so far, or lets Dropcontact call a webhook when the batch is done. A single-contact action wraps the submit-and-poll loop and can wait for the answer inside the step. The remaining credits are readable without spending any.

The connection holds a Dropcontact API access token, sent in the X-Access-Token header. Dropcontact charges on success only: a credit is spent when a verified email is returned or when an email you supply is verified.

Build with Dropcontact

Three routes to the same 7 actions. The Workflow tab is generated from Dropcontact's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.

Delete Default Webhook

delete-default-webhook

Remove the account's default webhook URL. Requests that carry their own webhook URL are unaffected.

Enrich Contact

enrich-contact

Find and verify the business email and company data of one contact. Needs an email, a LinkedIn URL, or a name plus company. Asynchronous at the vendor: set Wait seconds to poll for the answer inside this step, otherwise you get a request ID for Get Enrichment Result. Credits are charged only when a verified email is returned.

Get Credits Left

get-credits-left

Read the credits left on the access token. Sends one empty contact to the enrich endpoint, which the vendor documents as not consuming any credit.

Get Default Webhook

get-default-webhook

Read the account's default webhook URL, used for every enrichment request that does not set its own.

Get Enrichment Result

get-enrichment-result

Fetch the result of a batch by request ID. Returns ready: false while Dropcontact is still processing (retry in about 30 seconds), or set Force results to take what is done so far (unprocessed contacts come back unchanged).

Set Default Webhook

set-default-webhook

Set or replace the account's single default webhook URL. A request that carries its own webhook URL still takes precedence.

Submit Enrichment Batch

submit-enrichment-batch

Start an asynchronous enrichment of up to 250 contacts. Returns a request ID; fetch the result with Get Enrichment Result, or set a webhook URL. Dropcontact charges credits only for verified emails it returns, when the result is produced.

A workflow step names the app and the action, and the editor fills in the connection when you pick one. This is the Step shape from the workflow spec, carrying Dropcontact's real ids.

Every app-specific value here is a blank you have to fill in. An app action is reached through the connection that authenticates it, so the address is a connection id, not the app id — and connections belong to your account, so a public page cannot know yours. Create one for Dropcontact, then fill in the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the parameters that action declares. The call itself is real — the shape is transcribed from the studio's own snippet builder, which prints the same kind of blanks — but nothing in it is specific to Dropcontact. The Workflow tab is where this app's real ids are.

Install
npm install @w6w/sdk
yarn add @w6w/sdk
pnpm add @w6w/sdk
deno add npm:@w6w/sdk
Code
import { W6wClient, isActionRun } from "@w6w/sdk";

// Reads W6W_BASE_URL and W6W_TOKEN from the environment when omitted.
const client = new W6wClient();

const envelope = await client.run({
  urn: "conn_YOUR_CONNECTION_ID",
  action: "get-enrichment-result",
  payload: {
    requestId: "<value>",
    // forceResults: "<value>",
  },
});

if (isActionRun(envelope)) console.log(envelope.value);
Install the CLI
npm install -g @w6w/cli
CLI
w6w run conn_YOUR_CONNECTION_ID --action get-enrichment-result --payload '{"requestId":"<value>"}'

Give an AI agent Dropcontact — without giving it Dropcontact's credentials. One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.

One tool call
{
  "name": "w6w_invoke",
  "arguments": {
    "ref": "app:io.w6w.dropcontact#get-enrichment-result",
    "input": {
      "requestId": "<requestId>"
    }
  }
}

Every tool names its target with a single ref. The app: form above doesn't name a connection at all — the host resolves which of the caller's Dropcontact connections to sign with, and refuses rather than guesses when the answer is ambiguous.

What the agent gets

Credentials it can't read

The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.

A tool surface scoped to the caller

Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.

A durable workflow in one call

Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.

Health-aware discovery

Dropcontact's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.

The MCP surface is part of the hosted platform. Dropcontact itself is MIT, and the runtime that executes it is source-available (FSL).

Request MCP access

Health checks

Dropcontact declares its own checks, so its health is a property of the app rather than something the host guesses at.

service

Dropcontact status

Status of the `Dropcontact API` component on status.dropcontact.com (Statuspage). The web app, file, CRM and website components are shown but do not drive the verdict.

dependency

API reachable

Unauthenticated POST /v1/enrich/all. Dropcontact's JSON `No api key received` refusal passes: it proves the application is answering.

quota

Credits left

Remaining credits from the documented zero-cost POST /v1/enrich/all.
