# Tallied > Log hours and invoice clients from your AI chat. Tallied is an MCP server for time tracking and invoicing. Connect it to Claude, ChatGPT, or any MCP-compatible assistant and describe your work in plain language: it logs time entries against your clients and projects, reconstructs forgotten days from calendar and commit activity, reports hours and unbilled amounts, and drafts and sends invoices with a Stripe payment link — never sending anything to a client without your explicit approval in the conversation. ## MCP server - URL: https://withtallied.com/mcp - Transport: Streamable HTTP - Auth: OAuth 2.1 with dynamic client registration and PKCE - Discovery: https://withtallied.com/.well-known/oauth-authorization-server ## Tools - `time.list_entries` — list individual time entries for a day, week, project, or client - `time.report` — hours and billing totals, grouped by day, project, or client - `workspace.list_projects` — list clients, projects, aliases, and rates - `time.propose_entries` — propose time entries from calendar, commit, or ticket activity - `time.log_entry` — log one time entry - `time.log_entries_batch` — log several time entries at once - `time.update_entry` — edit an existing time entry - `time.delete_entry` — delete a time entry - `workspace.create_client` — create a client - `workspace.create_project` — create a project - `invoice.list` — list invoices by status, client, or date range - `invoice.get` — get one invoice's details - `invoice.preview_draft` — preview what an invoice would contain, without creating it - `invoice.create_draft` — create a draft invoice from unbilled hours - `invoice.record_payment` — record a payment made outside Stripe - `invoice.send` — email a reviewed draft invoice to the client with a payment link - `invoice.void` — cancel an invoice and release its time entries ## Docs - [Documentation](https://withtallied.com/docs) - [Support](https://withtallied.com/support) - [Privacy policy](https://withtallied.com/privacy) - [Terms of service](https://withtallied.com/terms)
