Tools that your AI agent can use through this MCP server to interact with Clockify

Update Time Entry

Updates an existing time entry in Clockify — change its start/end time, project, task, description, billable status, or tags. Clockify's update endpoint replaces the entire entry, so this action first fetches the current entry and merges your changes into it before saving — fields you don't set are left unchanged. Use List Time Entries to find the ID of the entry to update. See the documentation

Update Tag

Updates the name of an existing tag in a Clockify workspace. Use List Tags to find the ID of the tag to update. See the documentation

Update Invoice

Updates an existing invoice in a Clockify workspace. Clockify's update endpoint replaces the entire invoice, so this action first fetches the current invoice and merges your changes into it — fields you don't set are left unchanged, including the invoice's tax and discount percentages, which this action preserves but cannot edit. Status is applied through a separate endpoint, so it is sent as a second request after the field changes are saved, and setting it alone skips the replace entirely. Clockify offers no transaction across the two endpoints: if the status request fails, the field changes have already been applied. Line items and imported time cannot be set through Clockify's public API. Use List Invoices to find the ID of the invoice to update. See the documentation and the status endpoint

Update Client

Updates an existing client in a Clockify workspace. Set only the fields you want to change — Clockify's update endpoint replaces the whole client, so this action fetches the current record first and merges your changes into it. Use List Clients to find the ID of the client to update. See the documentation

Stop Timer

Stops the currently running timer for a workspace member in Clockify, setting its end time. See the documentation

Start Timer

Starts a running timer for a new time entry in Clockify — no end time is set. Use Stop Timer to stop it, or Update Time Entry to set an end time later. Use Log Time Entry instead if you already know both the start and end time. See the documentation, or starting for another member when User is set

Log Time Entry

Logs a completed time entry with an explicit start and end time in Clockify — use this to backfill time already tracked elsewhere. Use Start Timer instead if you want to start a running timer with no end time yet. See the documentation, or logging for another member when User is set

List Workspace Options

Lists the workspaces the authenticated user belongs to, as { label, value } pairs where value is the workspace ID that every other Clockify action requires. Call this first when you don't already know which workspace to operate on. See the documentation

List Time Entries

List all time entries in a Clockify workspace. See the documentation

List Tasks

Returns a single page of tasks in a Clockify project, optionally filtered by a substring of the task name or by active status. Tasks belong to a project, so set both Workspace and Project — use List Projects to find the project ID. Use the Page and Page Size inputs to page through results. See the documentation

List Tags

List all tags in a Clockify workspace. Optionally filter by a substring of the tag name, and page through results with the page and page size inputs. See the documentation

List Projects

List all projects in a Clockify workspace. See the documentation

List Invoices

Returns a single page of invoices in a Clockify workspace. Use the page and pageSize inputs to page through results. See the documentation

List Clients

List all clients in a Clockify workspace. Optionally filter by a substring of the client name or by archived status, and page through results with the page and page size inputs. See the documentation

Get Time Entry Report

Get a time entry report. See the documentation

Delete Tag

Deletes a tag from a Clockify workspace. This cannot be undone. Use List Tags to find the ID of the tag to delete. See the documentation

Delete Invoice

Deletes an invoice from a Clockify workspace. This cannot be undone. Use List Invoices to find the ID of the invoice to delete. See the documentation

Delete Client

Deletes a client from a Clockify workspace. This cannot be undone. Clockify only allows deleting archived clients, so this action archives the client first if it isn't already. Use List Clients to find the ID of the client to delete. See the documentation and the update endpoint used for the archive step

Create Tag

Creates a new tag in a Clockify workspace. Requires the tag name. See the documentation

Create Project

Creates a new project in a Clockify workspace. Only the name is required; link the project to a client so its time can be invoiced, and set an hourly rate to make tracked time billable at that rate. Use Add Task To Project afterwards to add the tasks that time entries are logged against. See the documentation

Create Invoice

Creates a new invoice for a client in a Clockify workspace. Set Import From and Import To to bill tracked time: the invoice is created and the time entries logged in that period are imported as line items. Leave both blank to create an empty invoice. The invoice is created first and the tracked time is imported in a second request, so if the import fails the invoice still exists and can be removed with Delete Invoice or retried. Chain Update Invoice afterwards to set the subject, note or status. See the documentation

Create Client

Creates a new client in a Clockify workspace. Requires a client name; address and note are optional. See the documentation

Add Task To Project

Adds a task to an existing project in a Clockify workspace. Tasks are the units of work that time entries are logged against, so create the task before calling Log Time Entry or Start Timer with a task. Optionally assign workspace members to it. Use List Projects to find the project ID. See the documentation

Add Members To Project

Adds member(s) to a project in Clockify. See the documentation
