Argorant for Claude Cowork
Delegate lead-list building to Claude Cowork.
Cowork is built for handing off whole tasks, not single prompts. Connect Argorant over MCP and 'build me a list of 500 verified heads of operations at mid-size European logistics companies' becomes a task Cowork can actually finish — sized, deduplicated, verified, and delivered as an export link.

Setup
Connect Claude Cowork to Argorant
Cowork speaks the Model Context Protocol natively, so the connection is a one-time setup:
1
Build a personalized 25-lead sample in Argorant.
2
In Claude Cowork, add a connector and point it at https://mcp.argorant.com/mcp.
3
Approve the OAuth prompt — the agent acts as your workspace, never as a shared account.
4
Delegate the task: describe the buyer, the geography, and how many contacts you need.
Lead generation with Claude Cowork
Hand Cowork the brief. Get back a finished, verified list.
Cowork shines when a task has real steps: resolve the industry, test a few segment definitions, compare counts, then commit credits to the best one. With Argorant's tool catalog it does all of that against 626.5M contacts — and because verification runs at export time, the list it hands back is checked the moment it's built, not whenever the database was last touched.

How many VP Sales contacts can we reach at SaaS companies in Germany?
→ suggest_industry·count_matches
8,412 VP-of-Sales contacts at software companies in Germany.
6,930 already verified · the rest verify live at export. Want me to prepare the list for your workspace owner to reveal?
Market sizing with Claude Cowork
Size a market before you spend a single credit.
Count matching contact records before spending contact credits. Cowork can refine supported seniority, industry and geography filters, then show a masked preview. These are contact counts, not unique-company or already-verified mailbox totals. If you need a company-size filter that the connected MCP tool does not expose, agree on a supported alternative or use the documented REST path.

validEmail verification with Claude Cowork
Every contact Cowork exports is verified at download time.
An agent that delivers bounced emails is worse than no agent. Argorant re-verifies addresses as the export is generated, so the file Cowork drops into your task thread reflects deliverability now. Bad addresses don't make the cut, and your sender reputation never pays for stale data.

CRM handoff from Claude Cowork
From delegated task to CSV, Smartlead, HubSpot, or Salesforce.
The last step of the task is the handoff. Cowork can finish by generating a time-boxed export link or pushing the segment toward your CRM and outreach stack — so 'build the list' and 'get it where the team works' are one delegation, not two tools and a copy-paste.

Add Argorant as a connector in Cowork using the MCP endpoint https://mcp.argorant.com/mcp, then sign in with OAuth. The whole setup takes about a minute and the agent inherits your workspace permissions and credit balance.
Yes — that's the point of pairing it with Argorant. Cowork can resolve industries from plain English, count candidate segments, reveal contacts, and produce a verified export, end to end, as one delegated task.
Searches and counts are free, so Cowork can explore as much as it needs. Credits are only drawn when contacts are revealed or exported, and every action is logged against your workspace so you can audit exactly what the agent did.
Exports are verified at the moment of download. Argorant continuously re-checks its 626.5M-contact database, and the export step runs a final deliverability pass so the file Cowork delivers is current.
