Read projects, tasks, comments, people and time entries; create tasks and comments in ProofHub. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the ProofHub connector, then ask in plain words. The AI picks the tools.
For project managers and team leads who run their work in ProofHub.
Search the tasks of the whole account, filtered by project, label or completion. Ask which open tasks are overdue or assigned to one person.
Open a project to see its status, dates and people. Then list its to-do lists and the tasks in each one.
Get one task with its description, dates, assignees and progress. Then list the comments on the task.
List the time entries of the account, page by page. List the people to see the role and email of each person.
Create a task in a to-do list, or post a comment on a task. Each call adds a new item, so do not retry blindly.
Changes dataMark one task completed, or open it again. Setting the same value twice has no further effect.
Changes dataThe login page asks for your ProofHub company and ProofHub API key.
Your company is the part before .proofhub.com in your address. Find your key under your profile menu → API access (the official docs also describe 5 clicks on the profile picture). The key acts as your user, so the assistant sees only what you can see.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"proofhub": {
"url": "https://proofhub.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"proofhub": {
"type": "http",
"url": "https://proofhub.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
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.
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 ProofHub company and ProofHub 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.

*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this ProofHub server only. Subscribe with proofhub_upgrade (it returns a Stripe Checkout link). Cancel any time with proofhub_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running proofhub_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 ProofHub. The server calls the ProofHub API with your own ProofHub 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 ProofHub company and ProofHub API key. 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 ProofHub company and ProofHub 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 ProofHub 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 ProofHub.
Yes, if you approve it. 3 of the 15 ProofHub tools can create or change data. The other 12 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 ProofHub server only. Cancel any time: Pro then runs to the end of the paid period. Run proofhub_usage_status to see how many calls you used.
Ask the AI to run proofhub_upgrade: it returns a Stripe Checkout link. To cancel, run proofhub_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 proofhub_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.
