Look up appointments, clients, services, staff and orders, and update clients in Boulevard. Hosted by usefulapi — connect from Claude, ChatGPT, 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": {
"boulevard": {
"url": "https://boulevard.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"boulevard": {
"type": "http",
"url": "https://boulevard.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
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 Client ID, Client secret and Business ID.
Optional: Boulevard environment.
Create an offline (machine-to-machine) app in the Boulevard Developer Portal and install it on your business. The portal shows the app's client ID and client secret (copy the secret as shown — it is already Base64); the business ID is the UUID of the business the app is installed on (a urn:blvd:Business:… id works too).
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 Client ID, Client secret and Business 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.
Turn on the Boulevard connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
boulevard_get_business | read | Get the business Fetch the Boulevard business the credentials act for — name, timezone, address, phone, website. A cheap way to confirm the setup works. GraphQL: business. |
boulevard_list_locations | read | List locations List the business's locations with id, name, timezone and address. Most other tools need a location id from here. GraphQL: locations. |
boulevard_list_appointments | read | List appointments List appointments at one location, optionally for one client and filtered by a query such as a date range or staff member. Each appointment includes its client, services, staff, state and cancellation. GraphQL: appointments. |
boulevard_get_appointment | read | Get one appointment Fetch one appointment by id — time, state, notes, client, each booked service with its staff and price (in cents), cancellation details and tags. GraphQL: appointment. |
boulevard_list_clients | read | List or search clients List the business's clients, or find them by email, id list, or a query (e.g. name = 'Jane Doe', mobilePhone = '+15551234567'). GraphQL: clients. |
boulevard_get_client | read | Get one client Fetch one client by id, including contact details, appointment count, account balance (cents), scheduling alert, tags and notes. GraphQL: client. |
boulevard_list_services | read | List services List the service menu — name, category, default duration (minutes) and default price (cents), and whether it is an add-on. GraphQL: services. |
boulevard_list_staff | read | List staff List staff members with their role, locations, contact details and whether they are bookable online, optionally filtered by a query. GraphQL: staff. |
boulevard_list_shifts | read | List staff shifts List staff working shifts at one location for a date range — clock-in/out times, weekday, availability and recurrence. GraphQL: shifts. |
boulevard_list_timeblocks | read | List timeblocks List blocked time on staff calendars at one location (breaks, meetings, personal time). GraphQL: timeblocks. |
boulevard_list_orders | read | List orders List checkout orders at one location with totals (cents: subtotal, discount, tax, gratuity, total, refunds), optionally filtered e.g. by closedAt range or clientId. GraphQL: orders. |
boulevard_get_order | read | Get one order Fetch one order by id with its totals and line items (services, products, gratuity, gift cards), amounts in cents. GraphQL: order. |
boulevard_list_products | read | List products List retail products — brand, SKU, barcode, unit price and cost (cents), category. Set include_inactive to include retired products. GraphQL: products. |
boulevard_list_memberships | read | List memberships List client memberships sold by the business — status (ACTIVE, PAUSED, PAST_DUE, CANCELLED), client, price (cents), interval, term and next charge date. GraphQL: memberships. |
boulevard_list_tags | read | List tags List the tags defined for the business (ids to use with boulevard_add_tag). GraphQL: tags. |
boulevard_create_client | write | Create a client Create a new client profile. Check boulevard_list_clients by email or phone first to avoid a duplicate. GraphQL: createClient. |
boulevard_update_client | write | Update a client Change a client's name, email, mobile phone, date of birth, pronoun or external id. Only the fields you pass change. GraphQL: updateClient. |
boulevard_create_client_note | write | Add a client note Add an internal note to a client's profile (visible to staff, e.g. formulas, preferences, allergies). GraphQL: createClientNote. |
boulevard_update_appointment | write | Update an appointment Replace an appointment's internal notes and/or move its state to BOOKED, CONFIRMED, ARRIVED or ACTIVE (e.g. confirm, or check the client in). Does not cancel or reschedule. GraphQL: updateAppointment. |
boulevard_create_timeblock | write | Block staff time Block time on one staff member's calendar at a location (a break, meeting or personal time) so it cannot be booked. One-off only. GraphQL: createTimeblock. |
boulevard_add_tag | write | Apply a tag Apply an existing tag (from boulevard_list_tags) to a taggable record such as a client or appointment. GraphQL: addTag. |
boulevard_usage_status | Usage status (free-tier meter) 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. | |
boulevard_request_feature | Request a missing feature Tell usefulapi that the user needs something the Boulevard 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. | |
boulevard_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Boulevard (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $19/month or $190/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
boulevard_cancel_subscription | Cancel the Pro subscription Cancel the caller's Boulevard 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 boulevard_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Boulevard server only. Subscribe with boulevard_upgrade (it returns a Stripe Checkout link). Cancel any time with boulevard_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running boulevard_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 Boulevard. The server calls the Boulevard API with your own Boulevard 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 Client ID, Client secret and Business ID. See Before you connect for where to find them.
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 Client ID, Client secret and Business 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Boulevard 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 Boulevard.
Yes, if you approve it. 6 of the 21 Boulevard 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.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Boulevard server only. Cancel any time: Pro then runs to the end of the paid period. Run boulevard_usage_status to see how many calls you used.
Ask the AI to run boulevard_upgrade: it returns a Stripe Checkout link. To cancel, run boulevard_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 boulevard_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.
