What you can do with WhatConverts in Claude and ChatGPT
For marketers and agencies who track calls, forms and other leads with WhatConverts.
Count leads by type and source for a period
The AI lists leads in a date range (calls, web forms, chats, texts and more) with source, medium, campaign and keyword. It groups and counts them for you.
Open one lead with its full details
The AI reads a lead with attribution, landing page, contact details, quote and sales value, and form or message content.
Read a phone call's transcript and recording links
The AI gets the duration, answer status, tracking and caller numbers, transcripts and links to the recording or voicemail. It returns links and text, not audio.
Review tracking phone numbers and web forms
The AI lists call-tracking numbers with destination, call flow and trigger, and the web forms that WhatConverts tracks.
Add a lead or update a lead's value
The AI adds a lead, such as an offline call or a sale from another system, or changes the quote value, sales value or quotable state of a lead.
Changes dataList an agency's accounts, profiles, users and roles
With an agency key, the AI lists client accounts and their profiles, users and roles. You can use the ids to filter leads.
How do I connect WhatConverts?
Before you connect
The login page asks for your API token and API secret.
In WhatConverts open Tracking → Integrations → API Keys inside a profile and click Generate API Key (a profile key sees that profile). Agency plans can use Integrations → API Keys in the agency dashboard for a master key that also reaches accounts, profiles and users. Your key is used only to call the WhatConverts API on your behalf; it is never shown to anyone.

Claude Code
Run this command, then run /mcp in Claude Code to log in:
Cursor
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"whatconverts": {
"url": "https://whatconverts.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"whatconverts": {
"type": "http",
"url": "https://whatconverts.usefulapi.io/mcp"
}
}
} Codex
Run these commands. The second one opens the login page:
Other clients
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your API token and API secret. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Pricing
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this WhatConverts server only. Ask your AI to run whatconverts_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with whatconverts_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with whatconverts_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

- List leads
whatconverts_list_leadsList tracked leads (phone calls, web forms, chats, texts, emails, events, transactions) with source/medium/campaign/keyword attribution, contact details, quote and sales values, call duration and transcripts. start_date is REQUIRED because WhatConverts otherwise returns only today's leads; a range is at most 400 days. A Profile key sees its own profile; an Agency key can narrow by account_id/profile_id. - Get lead
whatconverts_get_leadOne lead by id with every field: type, status, attribution (source, medium, campaign, keyword, landing page), contact details, location, device, quote/sales value, call details, transcripts, form/message content, and custom fields. - Get call recording info
whatconverts_get_call_recording_infoRecording and voicemail facts for a phone-call lead: the recording and voicemail links, call duration, answer status, tracking/caller numbers and the call/voicemail transcripts. Returns links and text only, never audio. Taken from GET /leads/{lead_id} (the audio endpoint GET /recording returns raw MP3 and is not used). - List accounts
whatconverts_list_accountsAgency key only: list the accounts (clients) of the agency with their profiles (id, name, date created). Use the ids to filter leads. start_date/end_date filter by creation date (WhatConverts defaults start_date to today, so pass an early start_date to see all). - Get account
whatconverts_get_accountAgency key only: one account by id with its profiles. - List profiles
whatconverts_list_profilesAgency key only: list the profiles (websites/campaign sets) of one account. start_date/end_date filter by creation date (WhatConverts defaults start_date to today, so pass an early start_date to see all). - Get profile
whatconverts_get_profileAgency key only: one profile by id (name, date created). - List users
whatconverts_list_usersAgency key only: list WhatConverts users (email, role, whether activation is pending) of the master account or of client accounts. start_date/end_date filter by creation date (WhatConverts defaults start_date to today, so pass an early start_date to see all). - Get user
whatconverts_get_userAgency key only: one user by id with role, notification settings and (for account users) the accounts they can access. - List roles
whatconverts_list_rolesAgency key only: list user roles (id, name, master-account or account type). - Get role
whatconverts_get_roleAgency key only: one role with its permission levels (none/view/edit) per area. - List tracking phone numbers
whatconverts_list_phone_numbersList the call-tracking numbers: tracking and destination number, call flow, trigger (source/medium), call recording and messaging flags, last used. A Profile key lists its own profile; an Agency key may filter by account_id/profile_id. - List tracked web forms
whatconverts_list_web_formsList the web forms WhatConverts tracks (id, name, how the form and its submit are matched on the page). A Profile key lists its own profile; an Agency key may filter by account_id/profile_id.

- Update lead
whatconverts_update_leadWRITE: update a lead's sales data in WhatConverts: quotable state, quote value, sales value, the URL where the lead occurred, and/or custom/additional field values. Only the fields you pass change; it overwrites the previous values of those fields. Sends no notifications. At least one field is required. - Create lead
whatconverts_create_leadWRITE: add a lead to WhatConverts, for example an offline phone call, a form submission from another system or a sale you want attributed. It appears in reports and counts toward lead totals; send_notification is always off, so no emails go out. Not idempotent: calling twice creates two leads. A Profile key adds to its own profile; an Agency key must pass profile_id.
Your usefulapi plan · 4
- Usage status (free-tier meter)
whatconverts_usage_statusReport the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. - Request a missing feature
whatconverts_request_featureTell usefulapi that the user needs something the WhatConverts tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. - Upgrade to Pro or Pro+
whatconverts_upgradeGet a paid plan for WhatConverts (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter. - Cancel the Pro subscription
whatconverts_cancel_subscriptionCancel the caller's WhatConverts Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run whatconverts_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with WhatConverts in Claude or ChatGPT?
Count leads by type and source for a period. Open one lead with its full details. Read a phone call's transcript and recording links. Review tracking phone numbers and web forms. Add a lead or update a lead's value. List an agency's accounts, profiles, users and roles. See what you can do for the details.
Is this an official WhatConverts product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by WhatConverts. The server calls the WhatConverts API with your own WhatConverts access, so it sees only the data that your account can see.
Can I connect WhatConverts to Claude or ChatGPT?
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
What do I need to connect?
The login page asks for your API token and API secret. See Before you connect for where to find them.
Do I put my WhatConverts key or an Authorization header in the client config?
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your API token and API secret. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
How do you keep my WhatConverts credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the WhatConverts API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in WhatConverts.
Can the AI change my WhatConverts data?
Yes, if you approve it. 2 of the 15 WhatConverts tools can create or change data. The other 13 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
What does it cost?
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this WhatConverts server only. Cancel any time: your paid plan then runs to the end of the paid period. Run whatconverts_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run whatconverts_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run whatconverts_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a WhatConverts tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with whatconverts_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Which AI clients can I use?
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
