Read WhatConverts leads, calls, forms, accounts and profiles; add leads and update lead value. Hosted by usefulapi — connect from Claude, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"whatconverts": {
"url": "https://whatconverts.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"whatconverts": {
"type": "http",
"url": "https://whatconverts.usefulapi.io/mcp"
}
}
}Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see 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.
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.
| Tool | Type | What it does |
|---|---|---|
whatconverts_list_leads | read | List leads List 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 /leads. |
whatconverts_get_lead | read | Get lead One 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 /leads/{lead_id}. |
whatconverts_get_call_recording_info | read | Get call recording info Recording 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). |
whatconverts_update_lead | write | Update lead WRITE: 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. POST /leads/{lead_id}. |
whatconverts_create_lead | write | Create lead WRITE: 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. POST /leads. |
whatconverts_list_accounts | read | List accounts Agency 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 /accounts. |
whatconverts_get_account | read | Get account Agency key only: one account by id with its profiles. GET /accounts/{account_id}. |
whatconverts_list_profiles | read | List profiles Agency 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 /accounts/{account_id}/profiles. |
whatconverts_get_profile | read | Get profile Agency key only: one profile by id (name, date created). GET /accounts/{account_id}/profiles/{profile_id}. |
whatconverts_list_users | read | List users Agency 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 /users. |
whatconverts_get_user | read | Get user Agency key only: one user by id with role, notification settings and (for account users) the accounts they can access. GET /users/{user_id}. |
whatconverts_list_roles | read | List roles Agency key only: list user roles (id, name, master-account or account type). GET /roles. |
whatconverts_get_role | read | Get role Agency key only: one role with its permission levels (none/view/edit) per area. GET /roles/{role_id}. |
whatconverts_list_phone_numbers | read | List tracking phone numbers List 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. GET /tracking/numbers. |
whatconverts_list_web_forms | read | List tracked web forms List 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. GET /tracking/forms. |
whatconverts_usage_status | Usage status (free-tier meter) Report the caller's current free-tier usage this month: calls used, monthly limit, remaining, and whether the cap is reached. Read-only; does not count against the meter. | |
whatconverts_request_feature | Request a missing feature Tell 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. | |
whatconverts_upgrade | Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED WhatConverts tool calls (the free tier caps monthly usage). Choose monthly ($9/month) or yearly ($90/year — 2 months free) billing. Returns a Stripe Checkout link to open in your browser; after payment your account upgrades automatically. Does not count against the meter. | |
whatconverts_cancel_subscription | Cancel the Pro subscription Cancel the caller's WhatConverts Pro subscription at the end of the paid period (no refund for the current period; unlimited calls continue 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. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 100 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited |
Pro covers this WhatConverts server only. Subscribe with whatconverts_upgrade (it returns a Stripe Checkout link). Cancel any time with whatconverts_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running whatconverts_upgrade before then undoes the cancel. Or write to [email protected].
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.
The login page asks for your API token and API secret. See Before you connect for where to find them.
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.
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.
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.
The Free plan gives 100 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this WhatConverts server only. Run whatconverts_usage_status to see how many calls you used.
Ask the AI to run whatconverts_upgrade: it returns a Stripe Checkout link. To cancel, run whatconverts_cancel_subscription. Pro continues to the end of the paid period.
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.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, 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.
