What you can do with Bilflo in Claude and ChatGPT

For staffing agencies that bill clients and pay contractors with Bilflo.

List our clients and their contacts

Lists clients with business name, client code and active flag, opens one client with its addresses and contacts, and lists a client's contacts.

Reads a contract job with client, contractor, dates and status, its pay and bill items such as Regular and Overtime, and who approves the timecards.

Check a client's billing setup

Lists a client's agreements, contract purchase orders, invoice groups and addresses, so you can see the billing terms in one place.

Update, terminate or reopen a contract job

Changes a job's title, overtime rule or flags, ends it on a date, or reopens a terminated job. Overtime rules can be listed first.

How do I connect Bilflo?

Before you connect

The login page asks for your Bilflo API key and Company ID.

Create the API key on the Credentials page of developer.bilflo.com. The Company ID is the GUID your staffing company was given for the API (ask support@bilflo.com if you do not have it). Your key is used only to call the Bilflo API on your behalf; it is never shown to anyone.

Claude claude.ai · Desktop

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

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 Bilflo and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://bilflo.usefulapi.io/mcp
ChatGPT opens the login page: enter your Bilflo API key and Company ID.
In Plugins, install Bilflo, 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 bilflo https://bilflo.usefulapi.io/mcp

Cursor

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

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

VS Code

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

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

Codex

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

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

codex mcp login bilflo

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://bilflo.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 Bilflo API key and Company ID. 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 Bilflo server only. Ask your AI to run bilflo_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 bilflo_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 bilflo_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Create clientbilflo_create_client
WRITE: creates a new client (customer) in Bilflo with the given business name and returns its id. It is visible to the whole staffing company and used for billing, so check bilflo_list_clients first to avoid a duplicate.
Update clientbilflo_update_client
WRITE: changes only the client fields you pass (business name, client code, phone, fax, active flag); the rest stay as they are. Setting is_active=false deactivates the client.
Update contract jobbilflo_update_contract_job
WRITE: changes only the contract job fields you pass (title, overtime rule, workers' comp code, burden, per-diem/expenses/sick-time/meal-period flags); the rest stay as they are. Pay and bill rates change payroll and invoices, so confirm values with the user. Client, contractor, dates and status cannot be changed here.
Terminate contract jobbilflo_terminate_contract_job
WRITE: ends a contract job on the given date (the contractor stops being placed with the client; no more timecards are expected after it). Affects payroll and invoicing. A terminated job can be brought back with bilflo_reopen_contract_job.
Reopen contract jobbilflo_reopen_contract_job
WRITE: reopens a terminated contract job (like the Open Job button): the job becomes active again, the end date is cleared, the contractor is made active and the missing timecards from the reopen date's week are created. Fails if the job is not terminated or the company plan has no room for another active job.
Update contractor contact detailsbilflo_update_contractor
WRITE: changes only the contractor contact fields you pass (name, title, email, phone, address, company); the rest stay as they are. Tax, bank, social security number and activation are not changeable here.

Your usefulapi plan · 4

Usage status (free-tier meter)bilflo_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 featurebilflo_request_feature
Tell usefulapi that the user needs something the Bilflo 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+bilflo_upgrade
Get a paid plan for Bilflo (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 subscriptionbilflo_cancel_subscription
Cancel the caller's Bilflo 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 bilflo_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Bilflo in Claude or ChatGPT?

List our clients and their contacts. Show a contract job with its pay and bill rates. Check a client's billing setup. Run a saved custom report. Update, terminate or reopen a contract job. Add or update a client. See what you can do for the details.

Is this an official Bilflo product?

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

Can I connect Bilflo 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 Bilflo API key and Company ID. See Before you connect for where to find them.

Do I put my Bilflo 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 Bilflo API key and Company ID. 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 Bilflo credentials?

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

Can the AI change my Bilflo data?

Yes, if you approve it. 6 of the 26 Bilflo tools can create or change data. The other 20 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 Bilflo server only. Cancel any time: your paid plan then runs to the end of the paid period. Run bilflo_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run bilflo_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 bilflo_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Bilflo tool that I need is missing?

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