Read GoCanvas forms, submissions, users, dispatches and reference data; create dispatches. 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": {
"gocanvas": {
"url": "https://gocanvas.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"gocanvas": {
"type": "http",
"url": "https://gocanvas.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 and Client secret.
In GoCanvas, open your profile → API Settings (administrator) and create an OAuth application; copy the client ID and the client secret (shown only once). API v3 is included in the Pro and Max plans or available as an add-on. The server acts as the user who owns the application and sees what that user can see. Your credentials are used only to call the GoCanvas API on your behalf and to derive a private account id.
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 and Client secret. 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 GoCanvas connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
gocanvas_get_me | read | Get the connected GoCanvas user The user who owns the connected OAuth application: id, login, company id and name, default department and role. Use it to learn the default department id. |
gocanvas_list_forms | read | List GoCanvas forms Forms (mobile form definitions) the connected user can see: id, name, status, version, department. Paged, 100 per page. Use gocanvas_get_form for a form's fields (entries). |
gocanvas_get_form | read | Get a GoCanvas form definition One form definition, including its screens and entries (field ids and labels). Use format 'flat' for the simplest list of fields (what you need to read submissions or create a dispatch), 'nested' (default) for the full structure, 'metadata' or 'minimal' for less. |
gocanvas_list_form_reports | read | List report definitions of a GoCanvas form The report (PDF) definitions attached to a form: id, name, format, whether emailed by default. Paged. |
gocanvas_list_submissions | read | List GoCanvas submissions Completed forms (submissions): id, form, number, created time, department, user, status. At least one of form_id, user_id or user_email is required (user_id and user_email cannot be combined). Default status is completed. Dates filter created_at. Paged, 100 per page. Use gocanvas_get_submission for the answers. |
gocanvas_get_submission | read | Get a GoCanvas submission One submission with all its responses (entry id, label, type, value). Accepts the numeric submission id or the client GUID. |
gocanvas_list_submission_revisions | read | List revisions of a GoCanvas submission The revision history of a submission (who changed it and when). Paged. |
gocanvas_list_users | read | List GoCanvas users Users of the company: id, name, email, enabled. Paged, 100 per page. |
gocanvas_get_user | read | Get a GoCanvas user One user by id: name, login, contact data, default department and role. |
gocanvas_list_departments | read | List GoCanvas departments Departments of the company: id, name, description. The pseudo department -1 'All' is included. |
gocanvas_list_department_users | read | List users of a GoCanvas department The users in one department with their department role. |
gocanvas_list_dispatches | read | List GoCanvas dispatches Dispatches (jobs sent to field workers): id, form, assignee, status, schedule. At least one of user_id, department_id or form_id is required. Dates are ISO-8601. Paged. |
gocanvas_get_dispatch | read | Get a GoCanvas dispatch One dispatch by id with its pre-filled responses, schedule and status. |
gocanvas_list_customers | read | List GoCanvas customers Customers (contacts of the Project Management view): individuals or businesses, optionally tied to a site. Paged. |
gocanvas_list_projects | read | List GoCanvas projects Projects of the Project Management view. Paged. |
gocanvas_list_sites | read | List GoCanvas sites Sites (job locations) of the Project Management view. Paged. |
gocanvas_list_reference_data | read | List GoCanvas reference data sets Reference data (lookup tables used by forms): id, name, columns, version. Without department_id the user's default department is used. |
gocanvas_get_reference_data | read | Get a GoCanvas reference data set One reference data set with its rows. |
gocanvas_list_groups | read | List GoCanvas groups User groups: id, name, and the forms and users assigned. Paged. |
gocanvas_list_workflows | read | List GoCanvas workflows Workflows (handoff chains between users) the connected user takes part in, with their handoff states and the count of tasks available to claim. Paged. |
gocanvas_list_locations | read | List GoCanvas tracker locations GPS location events of field users (needs the tracker feature). start_date and end_date are required and may span at most 7 days. Omit user_id for all users of the company. Paged. |
gocanvas_create_dispatch | write | Create a GoCanvas dispatch WRITE: creates a dispatch, a job that appears on the assignee's mobile device (immediate_dispatch is sent at once, with a push notification when send_notification is true; scheduled_dispatch needs scheduled_at and scheduled_end). Responses pre-fill the assignee's form (entry ids from gocanvas_get_form). Without assignee_id the dispatch stays unassigned. Not idempotent: calling twice creates two dispatches. Media fields cannot be pre-filled. |
gocanvas_mark_dispatch_received | write | Mark a GoCanvas dispatch as received WRITE: acknowledges a dispatch (status becomes received). Only works for a dispatch in the assigned state that is assigned to the connected user; repeating it is refused by GoCanvas. |
gocanvas_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. | |
gocanvas_request_feature | Request a missing feature Tell usefulapi that the user needs something the GoCanvas 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. | |
gocanvas_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on GoCanvas (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. | |
gocanvas_cancel_subscription | Cancel the Pro subscription Cancel the caller's GoCanvas 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 gocanvas_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 GoCanvas server only. Subscribe with gocanvas_upgrade (it returns a Stripe Checkout link). Cancel any time with gocanvas_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running gocanvas_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 GoCanvas. The server calls the GoCanvas API with your own GoCanvas 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 and Client secret. 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 and Client secret. 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 GoCanvas 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 GoCanvas.
Yes, if you approve it. 2 of the 23 GoCanvas tools can create or change data. The other 21 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 GoCanvas server only. Cancel any time: Pro then runs to the end of the paid period. Run gocanvas_usage_status to see how many calls you used.
Ask the AI to run gocanvas_upgrade: it returns a Stripe Checkout link. To cancel, run gocanvas_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 gocanvas_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.
