What you can do with Cyberimpact in Claude and ChatGPT
For marketers and small businesses who send email newsletters with Cyberimpact.
Compare the results of your recent mailings
The AI lists sent mailings and reads each one's delivery, view and click rates and per-link clicks. You see which mailings did best.
Find hard-bounced and unsubscribed addresses
The AI lists members whose last mailing hard-bounced, with the bounce date, and members who unsubscribed. You get a clean-up list.
See your groups and who is in them
The AI lists groups with member and mailing counts, and lists the members of one group.
Check one member's groups, mailings and consent
The AI reads a member by email: attributes, groups, mailings received, opened and clicked, and the consent record with type and date.
Add or update members and their groups, or send opt-ins
The AI adds a member who gave consent, or sends an opt-in email so the person joins a group after confirming. It can also update a member or add one to more groups.
Changes dataSchedule a mailing to chosen groups
The AI checks the groups and templates, then schedules a mailing for a send time. It goes to every member of the chosen groups unless you cancel it in the app.
Changes dataHow do I connect Cyberimpact?
Before you connect
The login page asks for your Cyberimpact API token.
In Cyberimpact open Developers → API tokens and create a token (a long text with two dots in it). It acts with your account's rights and can be revoked there at any time. Your token is used only to call the Cyberimpact API on your behalf; it is never shown to anyone. This is a token for integrations, not your Cyberimpact password.

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": {
"cyberimpact": {
"url": "https://cyberimpact.usefulapi.io/mcp"
}
}
} VS Code
Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"cyberimpact": {
"type": "http",
"url": "https://cyberimpact.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 Cyberimpact API token. 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 Cyberimpact server only. Ask your AI to run cyberimpact_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 cyberimpact_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 cyberimpact_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

- Add member
cyberimpact_add_memberWRITE: add a contact as a subscribed member WITHOUT a confirmation email (implied consent) and put it in the given groups; the contact can then be mailed. Only use it for people who really gave their consent (CASL); to ask the person to confirm first use cyberimpact_send_optin. A member that already exists is rejected by the API. Throttled by Cyberimpact; for many contacts use the app's import. - Update member
cyberimpact_update_memberWRITE: change only the given attributes of a member (other attributes stay as they are). The old values of the changed fields are overwritten and not recoverable through the API. Set new_email to change the address. - Add member to groups
cyberimpact_add_member_to_groupsWRITE: add an existing member to more groups (existing group memberships are kept). Being in a group makes the member a recipient of mailings sent to it. Returns the member's groups after the update. - Send opt-in email
cyberimpact_send_optinWRITE, SENDS AN EMAIL to the given address: an opt-in confirmation request. The person is added to the groups only after they confirm (the member is created if it does not exist). Use this instead of cyberimpact_add_member when you do not have the person's consent yet. Only call it after the user has approved sending to this address, and set confirm_send to true. Throttled by Cyberimpact. - Create group
cyberimpact_create_groupWRITE: create a new, empty group (mailing list). A public group can be offered on subscription forms; a private one is internal. Groups cannot be deleted through this server. - Create template
cyberimpact_create_templateWRITE: create a new email template from HTML and/or text. It is only saved in the account; nothing is sent. - Schedule mailing
cyberimpact_create_mailingWRITE, SENDS EMAIL TO CUSTOMERS: create a mailing scheduled to be sent at send_at to every member of the chosen groups. It goes out for real unless it is cancelled in the Cyberimpact app before send_at. Only call it after the user has approved the subject, body, sender and groups, and set confirm_send to true. mail_from must be a validated sender address of the account. A mailing cannot be deleted through this server.
Your usefulapi plan · 4
- Usage status (free-tier meter)
cyberimpact_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
cyberimpact_request_featureTell usefulapi that the user needs something the Cyberimpact 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+
cyberimpact_upgradeGet a paid plan for Cyberimpact (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
cyberimpact_cancel_subscriptionCancel the caller's Cyberimpact 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 cyberimpact_upgrade later to undo the cancel before the period ends. Does not count against the meter.
FAQ
What can I do with Cyberimpact in Claude or ChatGPT?
Compare the results of your recent mailings. Find hard-bounced and unsubscribed addresses. See your groups and who is in them. Check one member's groups, mailings and consent. Add or update members and their groups, or send opt-ins. Schedule a mailing to chosen groups. See what you can do for the details.
Is this an official Cyberimpact product?
No. usefulapi is an independent service. It is not affiliated with or endorsed by Cyberimpact. The server calls the Cyberimpact API with your own Cyberimpact access, so it sees only the data that your account can see.
Can I connect Cyberimpact 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 Cyberimpact API token. See Before you connect for where to find it.
Do I put my Cyberimpact 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 Cyberimpact API token. 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 Cyberimpact credentials?
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Cyberimpact 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 Cyberimpact.
Can the AI change my Cyberimpact data?
Yes, if you approve it. 7 of the 25 Cyberimpact tools can create or change data. The other 18 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 Cyberimpact server only. Cancel any time: your paid plan then runs to the end of the paid period. Run cyberimpact_usage_status to see how many calls you used.
How do I subscribe or cancel?
Ask the AI to run cyberimpact_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 cyberimpact_cancel_subscription. Your paid plan continues to the end of the paid period.
What if a Cyberimpact tool that I need is missing?
Tell the AI what you wanted to do. It can send the request with cyberimpact_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.
