What you can do with Paymo in Claude and ChatGPT

For freelancers and small teams who track projects, time and invoices in Paymo.

Add up hours logged by your team

The AI lists time entries for a date range, user or project and adds up the durations. You see how many hours went into which project.

Find overdue tasks and who has them

The AI lists tasks by project, task list, assignee or completion and checks their due dates. It shows which tasks are late and who is assigned.

Check unpaid invoices by client

The AI lists invoices with status, due date and total and reads one with its line items and payments. It matches them to clients.

Log or edit time, or start and stop a timer

The AI logs a finished time entry on a task by date and duration or by start and end, or starts and stops a running timer. It can also edit an entry.

Changes data

Create or update a task and add a comment

The AI creates a task in a task list or project, or renames, reassigns, re-dates or completes one. It can also comment on the task.

Changes data

Set up a new project for a client

The AI creates a project for a client you pick from the client list.

How do I connect Paymo?

Before you connect

The login page asks for your Paymo API key.

In Paymo, open My account → API keys and click Generate new API key. The key acts as you (your projects and permissions). It is used only to call the Paymo API on your behalf and to derive a private account id; it is never shown to anyone.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name Paymo and this URL, then click Add:
https://paymo.usefulapi.io/mcp
Claude opens the login page: enter your Paymo API key.
In a chat, click + → Connectors and turn on Paymo.

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

ChatGPT chatgpt.com

Open Plugins, click +, then Add custom MCP server.
Enter the name Paymo and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://paymo.usefulapi.io/mcp
ChatGPT opens the login page: enter your Paymo API key.
In Plugins, install Paymo, 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 paymo https://paymo.usefulapi.io/mcp

Cursor

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

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

VS Code

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

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

Codex

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

codex mcp add paymo --url https://paymo.usefulapi.io/mcp

codex mcp login paymo

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://paymo.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 Paymo 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.

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 Paymo server only. Ask your AI to run paymo_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 paymo_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 paymo_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4

Usage status (free-tier meter)paymo_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 featurepaymo_request_feature
Tell usefulapi that the user needs something the Paymo 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+paymo_upgrade
Get a paid plan for Paymo (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 subscriptionpaymo_cancel_subscription
Cancel the caller's Paymo 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 paymo_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Paymo in Claude or ChatGPT?

Add up hours logged by your team. Find overdue tasks and who has them. Check unpaid invoices by client. Log or edit time, or start and stop a timer. Create or update a task and add a comment. Set up a new project for a client. See what you can do for the details.

Is this an official Paymo product?

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

Can I connect Paymo 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 Paymo API key. See Before you connect for where to find it.

Do I put my Paymo 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 Paymo 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.

How do you keep my Paymo credentials?

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

Can the AI change my Paymo data?

Yes, if you approve it. 8 of the 21 Paymo 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 Paymo server only. Cancel any time: your paid plan then runs to the end of the paid period. Run paymo_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run paymo_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 paymo_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Paymo tool that I need is missing?

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