Read workspaces, tasks and time entries, create and update tasks, and log time in Kantata. For agencies and project teams that run client workspaces and track time in Kantata OX. 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": {
"kantata": {
"url": "https://kantata.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"kantata": {
"type": "http",
"url": "https://kantata.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.
List the workspaces the token can see, then read one workspace's dates, status and participants.
kantata_list_workspaces kantata_get_workspace
List tasks filtered by workspace, assignee or due date, then read one task's description and checklist.
kantata_list_stories kantata_get_story
List time entries by workspace, user or date range, and check the status of timesheet submissions.
kantata_list_time_entries kantata_list_timesheet_submissions
Create a task in a workspace, or log time against a task. Each call creates a new record.

The login page asks for your Kantata OX OAuth token.
In Kantata OX, open Settings → API → Registered Applications, choose your application and select Show OAuth Token. You need a paid Kantata OX account and the Account Administrator role. The token acts as one Kantata user in one account. It is used only to call the API on your behalf.
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 Kantata OX OAuth token. 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 Kantata connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
kantata_get_current_user | read | Get the current user Return the Kantata OX user that the token belongs to, with name, email, role and account membership. Good first call to confirm the connection. Kantata API: GET /api/v1/users/me. |
kantata_list_users | read | List users List the users visible to the token, optionally filtered by a search string. Use the returned user ids in other tools. Kantata API: GET /api/v1/users. |
kantata_list_organizations | read | List organizations List client and partner organizations visible to the token. Kantata API: GET /api/v1/organizations. |
kantata_list_workspaces | read | List workspaces List workspaces (projects) visible to the token, with title, dates, status and participants. Kantata API: GET /api/v1/workspaces. |
kantata_get_workspace | read | Get a workspace Get one workspace (project) by id, with title, dates, budget fields and participants. Kantata API: GET /api/v1/workspaces/{id}. |
kantata_list_stories | read | List stories (tasks) List stories (tasks) with title, status, due date, assignees and completion. Filter by workspace, assignee, completion or due dates. Kantata API: GET /api/v1/stories. |
kantata_get_story | read | Get a story (task) Get one story (task) by id, with its description, dates, assignees, status and checklist. Kantata API: GET /api/v1/stories/{id}. |
kantata_create_story | write | Create a story (task) Create a story (task) in a workspace. Writes data: creates a new task each call. Kantata API: POST /api/v1/stories. |
kantata_update_story | write | Update a story (task) Change the title, description or dates of an existing story (task). Only the fields you pass change. Writes data. Kantata API: PUT /api/v1/stories/{id}. |
kantata_list_time_entries | read | List time entries List logged time entries with minutes, date performed, user, story and billable flag. Filter by workspace, user or date range. Kantata API: GET /api/v1/time_entries. |
kantata_list_timesheet_submissions | read | List timesheet submissions List timesheet submissions with their status and period, filtered by workspace, user or dates. Kantata API: GET /api/v1/timesheet_submissions. |
kantata_log_time | write | Log time Log a time entry against a workspace, optionally a story. Writes data: creates a new entry each call, so do not retry it blindly. Kantata API: POST /api/v1/time_entries. |
kantata_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. | |
kantata_request_feature | Request a missing feature Tell usefulapi that the user needs something the Kantata 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. | |
kantata_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Kantata (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+, $39/month or $390/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. | |
kantata_cancel_subscription | Cancel the Pro subscription Cancel the caller's Kantata 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 kantata_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 Kantata server only. Subscribe with kantata_upgrade (it returns a Stripe Checkout link). Cancel any time with kantata_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running kantata_upgrade before then undoes the cancel. Or write to [email protected].
Check open workspaces and their due dates. Review open tasks for the week. Check who logged time last month. Create a task or log time. See what you can do for the details.
No. usefulapi is an independent service. It is not affiliated with or endorsed by Kantata. The server calls the Kantata API with your own Kantata 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 Kantata OX OAuth token. 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 Kantata OX OAuth token. 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 Kantata 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 Kantata.
Yes, if you approve it. 3 of the 12 Kantata tools can create or change data. The other 9 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 Kantata server only. Cancel any time: Pro then runs to the end of the paid period. Run kantata_usage_status to see how many calls you used.
Ask the AI to run kantata_upgrade: it returns a Stripe Checkout link. To cancel, run kantata_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 kantata_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.
