What you can do with Trengo in Claude and ChatGPT

For customer support teams who handle tickets and messages across channels in Trengo.

Find open tickets and who they are from

The AI lists tickets filtered by status, contact, assignee, channel or label, with the latest message, so you see what needs an answer.

Read a ticket and summarize the conversation

The AI lists the messages of a ticket, including inbound, outbound and internal notes, and summarizes what the customer wants.

Report on ticket volume and agent performance

The AI reads support metrics for a period, such as created and closed tickets and response times, and per-agent figures, so you see which agent closed the most.

Look up, create or update a contact

The AI searches contacts by name, email or phone, opens one, or creates a contact on a channel and sets the contact groups.

Changes data

Assign, close or reopen a ticket

The AI assigns a ticket to a user or team, closes it with a ticket result such as Resolved, or reopens a closed ticket.

Changes data

Create a ticket, add a note or reply to a customer

The AI creates a ticket for a contact, and posts an internal note or a message that is delivered to the customer on the ticket's channel.

How do I connect Trengo?

Before you connect

The login page asks for your Trengo personal access token.

Create one in Trengo → Settings → Apps & integrations → Rest API → new personal access token. It acts with your own Trengo permissions, channels and teams. Your token is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.

Claude claude.ai · Desktop

  1. Open Customize → Connectors, then click + Add → Add custom connector.
  2. Enter the name Trengo and this URL, then click Add:
    https://trengo.usefulapi.io/mcp
  3. Claude opens the login page: enter your Trengo personal access token.
  4. In a chat, click + → Connectors and turn on Trengo.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

  1. Open Plugins, click +, then Add custom MCP server.
  2. Enter the name Trengo and this URL, choose OAuth as the authentication, confirm the warning and create it:
    https://trengo.usefulapi.io/mcp
  3. ChatGPT opens the login page: enter your Trengo personal access token.
  4. In Plugins, install Trengo, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http trengo https://trengo.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "trengo": {
      "url": "https://trengo.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "trengo": {
      "type": "http",
      "url": "https://trengo.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add trengo --url https://trengo.usefulapi.io/mcp
codex mcp login trengo

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.

https://trengo.usefulapi.io/mcp

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 Trengo personal access 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

PlanPriceLimit
Free$050 tool calls / month
Proper user$9/mo · $90/yr10,000 tool calls / month
Pro+per user$39/mo · $390/yr100,000 tool calls / month

Each paid plan covers this Trengo server only. Ask your AI to run trengo_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 trengo_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 trengo_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4

  • Usage status (free-tier meter)trengo_usage_status
    Report 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 featuretrengo_request_feature
    Tell usefulapi that the user needs something the Trengo 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+trengo_upgrade
    Get a paid plan for Trengo (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 subscriptiontrengo_cancel_subscription
    Cancel the caller's Trengo 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 trengo_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Trengo in Claude or ChatGPT?

Find open tickets and who they are from. Read a ticket and summarize the conversation. Report on ticket volume and agent performance. Look up, create or update a contact. Assign, close or reopen a ticket. Create a ticket, add a note or reply to a customer. See what you can do for the details.

Is this an official Trengo product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Trengo. The server calls the Trengo API with your own Trengo access, so it sees only the data that your account can see.

Can I connect Trengo 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 Trengo personal access token. See Before you connect for where to find it.

Do I put my Trengo 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 Trengo personal access 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 Trengo credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Trengo 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 Trengo.

Can the AI change my Trengo data?

Yes, if you approve it. 9 of the 24 Trengo tools can create or change data. The other 15 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 Trengo server only. Cancel any time: your paid plan then runs to the end of the paid period. Run trengo_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run trengo_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 trengo_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Trengo tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with trengo_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.
