Start and stop timers, log time entries, and read projects, tasks and time entries in solidtime. For freelancers and small teams that track time against projects in solidtime. 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": {
"solidtime": {
"url": "https://solidtime.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"solidtime": {
"type": "http",
"url": "https://solidtime.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.
Check the running timer, start a timer for a member, or stop the timer that runs now.
Changes data · solidtime_get_active_timer solidtime_start_timer solidtime_stop_timer
Log a time entry with a start and an end for a member. Read the organizations first to get the member id.
Changes data · solidtime_list_organizations solidtime_create_time_entry
List the time entries of a time window, then read the projects and clients they belong to.
solidtime_list_time_entries solidtime_list_projects solidtime_list_clients
List the tasks of a project. Done tasks stay hidden unless you ask for them.
solidtime_list_tasks solidtime_get_project
The login page asks for your solidtime API token.
Create it in solidtime → Profile Settings → Create API Token. The token is shown once. It is used only to call the 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 solidtime API 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 solidtime connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
solidtime_get_current_user | read | Get my user Return the signed-in solidtime user: id, name, email, timezone and week start. Use it to check the connection. solidtime API: GET /v1/users/me. |
solidtime_list_organizations | read | List my organizations List the organizations (workspaces) you belong to, with your role. Each item's id is the member_id for time entries in that organization. solidtime API: GET /v1/users/me/memberships. |
solidtime_get_active_timer | read | Get the running timer Return the time entry that is running now (no end time), or say that no timer runs. solidtime API: GET /v1/users/me/time-entries/active. |
solidtime_list_projects | read | List projects List projects in an organization. Archived projects are hidden unless archived is true or all. solidtime API: GET /v1/organizations/{organization}/projects. |
solidtime_get_project | read | Get a project Return one project: name, client, billable flag, estimated and spent time. solidtime API: GET /v1/organizations/{organization}/projects/{project}. |
solidtime_list_clients | read | List clients List clients in an organization. solidtime API: GET /v1/organizations/{organization}/clients. |
solidtime_list_tags | read | List tags List tags in an organization. Use the tag ids in time entries. solidtime API: GET /v1/organizations/{organization}/tags. |
solidtime_list_tasks | read | List tasks List tasks in an organization, optionally for one project. Done tasks are hidden unless done is true or all. solidtime API: GET /v1/organizations/{organization}/tasks. |
solidtime_list_time_entries | read | List time entries List time entries in an organization, newest first. Filter by member, time window, running or billable state. At most 500 per call; use offset to page. solidtime API: GET /v1/organizations/{organization}/time-entries. |
solidtime_start_timer | write | Start a timer Start a timer now for a member. The API refuses a second running timer (time_entry_still_running), so stop the running timer first with solidtime_stop_timer. solidtime API: POST /v1/organizations/{organization}/time-entries. |
solidtime_stop_timer | write | Stop the running timer Stop the timer that runs now, setting its end to the current UTC time. Fails when no timer runs. Reads the running entry first, then updates it. solidtime API: GET /v1/users/me/time-entries/active, PUT /v1/organizations/{organization}/time-entries/{timeEntry}. |
solidtime_create_time_entry | write | Log a time entry Log a finished time entry with a start and an end, for a member. Use solidtime_start_timer for a running one. solidtime API: POST /v1/organizations/{organization}/time-entries. |
solidtime_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. | |
solidtime_request_feature | Request a missing feature Tell usefulapi that the user needs something the solidtime 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. | |
solidtime_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on solidtime (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. | |
solidtime_cancel_subscription | Cancel the Pro subscription Cancel the caller's solidtime 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 solidtime_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 solidtime server only. Subscribe with solidtime_upgrade (it returns a Stripe Checkout link). Cancel any time with solidtime_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running solidtime_upgrade before then undoes the cancel. Or write to [email protected].
Start or stop a timer. Log a finished time entry. Review tracked time by project. Find open tasks in a project. See what you can do for the details.
No. usefulapi is an independent service. It is not affiliated with or endorsed by solidtime. The server calls the solidtime API with your own solidtime 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 solidtime API 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 solidtime API 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 solidtime 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 solidtime.
Yes, if you approve it. 3 of the 12 solidtime 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 solidtime server only. Cancel any time: Pro then runs to the end of the paid period. Run solidtime_usage_status to see how many calls you used.
Ask the AI to run solidtime_upgrade: it returns a Stripe Checkout link. To cancel, run solidtime_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 solidtime_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.
