Manage Encharge people, tags, segments and fields, and track events for email automation. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the Encharge connector, then ask in plain words. The AI picks the tools.
For SaaS marketers who run email automation and track people in Encharge.
The AI looks up up to 20 people by email, userId or Encharge id and returns all fields, tags and segment data. You get a quick profile of each person.
The AI lists the dynamic segments with their conditions, then lists the people in one segment with paging and chosen person fields.
The AI lists all person fields, built-in and custom, with name, title, type and whether the field is read-only. It helps before you update people.
The AI adds tags to a person, removes tags, or unsubscribes the person so Encharge sends no more email. The person stays in Encharge.
Changes dataThe AI creates a person or updates the one with the same email, userId or Encharge id, and can record an event such as "Registered user" for a person. Only the fields you pass are set.
Changes dataThe login page asks for your Encharge API key.
Optional: Write key (optional, for tracking events).
Find the API key and the write key in Encharge → Account → Account info. The API key needs a plan with API access. The write key is optional: only the event tracking tool uses it. Your keys are used only to call the Encharge API on your behalf; they are never shown to anyone.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"encharge": {
"url": "https://encharge.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"encharge": {
"type": "http",
"url": "https://encharge.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
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 Encharge API key. 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.
| 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 Encharge server only. Ask your AI to run encharge_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 encharge_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 encharge_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

No. usefulapi is an independent service. It is not affiliated with or endorsed by Encharge. The server calls the Encharge API with your own Encharge access, so it sees only the data that your account can see.
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.
The login page asks for your Encharge API key. See Before you connect for where to find it.
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 Encharge API key. 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 Encharge 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 Encharge.
Yes, if you approve it. 5 of the 10 Encharge tools can create or change data. The other 5 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
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 Encharge server only. Cancel any time: your paid plan then runs to the end of the paid period. Run encharge_usage_status to see how many calls you used.
Ask the AI to run encharge_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 encharge_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with encharge_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, 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.
