Read Bill4Time clients, projects, time entries, expenses, invoices, payments, users and contacts. 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": {
"bill4time": {
"url": "https://bill4time.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"bill4time": {
"type": "http",
"url": "https://bill4time.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 Bill4Time API key.
Create it in Bill4Time under Settings → API tab. Use a v1 key. The key gives read access to your firm's billing data; this server only reads, and returns no private notes unless you ask. Your key is used only to call the Bill4Time API on your behalf; it is never shown to anyone. Delete the key in Bill4Time to disconnect.
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 Bill4Time 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.

bill4time_request_feature | Request a missing feature Tell usefulapi that the user needs something the Bill4Time 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. | |
bill4time_upgrade | Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED Bill4Time 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. | |
bill4time_cancel_subscription | Cancel the Pro subscription Cancel the caller's Bill4Time 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 bill4time_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 API key | $9/mo · $90/yr | Unlimited |
Pro covers this Bill4Time server only. Subscribe with bill4time_upgrade (it returns a Stripe Checkout link). Cancel any time with bill4time_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running bill4time_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 Bill4Time. The server calls the Bill4Time API with your own Bill4Time access, so it sees only the data that your account can see.
The login page asks for your Bill4Time 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 Bill4Time 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 Bill4Time 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 Bill4Time.
All 8 Bill4Time tools are marked read-only.
The Free plan gives 100 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this Bill4Time server only. Run bill4time_usage_status to see how many calls you used.
Ask the AI to run bill4time_upgrade: it returns a Stripe Checkout link. To cancel, run bill4time_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 bill4time_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.
