Tools
Every MCP tool with what it does, its annotations and what it can cost.
Names are exact. A client may prefix them (for example mcp__argorant__argorant_count_people).
Hints tell your AI app how careful to be. read-only tools only look at your own data: they change nothing, spend nothing and contact no one, so the app can run them without asking. Every tool that spends credits, sends email or changes something keeps asking for your approval.
Read and preview
| Tool | What it does | Hints |

Reveal, enrich, export
| Tool | What it does | Hints |
|---|---|---|
argorant_reveal_people | Shows the full contact details of a small group of people: name, work email and profile link. 1 credit per person whose working email is new to you. With include_phones it also adds phone numbers: 10 credits per phone number returned, nothing if none is found. | destructive, open-world |
argorant_enrich | Looks up one person by email, or by name and company domain, or one company by its domain. 1 credit for a new working email; a company lookup is free. With include_phones it also adds the person's phone number: 10 credits if one is found, nothing if not. | destructive, open-world |
argorant_create_export | Makes a spreadsheet (CSV) of everyone who matches a search. 1 credit per person with a working email. With include_phones, each phone number in the file costs 10 more credits. | destructive, open-world |
argorant_export_status | Shows how far an export is and whether it is ready. | read-only |
argorant_export_batch_status | Shows how far a large export, split into several files, is. | read-only |
argorant_download_export_preview | Reads the first part of a finished export file. It shows real contact details. | safe |
Phone numbers
Phone numbers (direct dials and mobiles) are never included unless you ask for them. Your AI app adds them only when it sets include_phones on argorant_reveal_people, argorant_enrich, argorant_create_export or argorant_export_list, and it asks you first.
- A phone number costs 10 credits, and only when a number is actually returned.
- People without a number cost nothing.
- Numbers you already unlocked, in the app, the API, the CLI or here, are free.
- Phone numbers come with the Pro plan and higher.
- Every result says, per person, whether a number came back and what it cost.
Company and HQ numbers stay free where Argorant already shows them. The same rule applies in the app and in the API (POST /api/v1/people/phones).

Credits
Argorant is the cheapest way to get validated B2B contacts. Compare the packs below with our comparison pages. The assistant shows you the price and buys only after your explicit yes. You get a payment link that you pay yourself, unless your workspace allows the saved card, which is then charged within the limits you set in Settings.
| Tool | What it does | Hints |
|---|---|---|
argorant_credit_packs | Shows the credit packs and their prices: 500 for $17.50, 5,000 for $69, 25,000 for $199, 100,000 for $499. | read-only |

Send to other tools
Connect the sending tool you already use once in Argorant, under Settings, Integrations, with that tool's own API key. The assistant never asks for that key. It can then send a campaign's people or an export into one of your campaigns there. People who bounced, unsubscribed or are blocked are never sent, and your campaign there is not started.
| Tool | What it does | Hints |
|---|---|---|
argorant_list_integrations | Shows the tools you connected, and the campaigns inside one of them. | read-only |
argorant_push_to_integration | After your yes, sends a campaign's people or an export into a campaign in a connected tool. Free from the Pro plan; an export costs credits when it runs. | open-world |
argorant_integration_push_status | Shows how a send stands and how many people went over. | read-only |
Parameters for each campaign and inbox tool mirror the REST endpoints in the API reference; the data tools take the shared filters.
