Rinkta MCP: AI agent time tracking and invoicing | Rinkta [Rinkta](https://rinkta.com/) Products Agencies Resources [Customers](https://rinkta.com/case-studies) [Pricing](https://rinkta.com/pricing) [Log in](https://app.rinkta.com/session/new) [Sign up for free](https://app.rinkta.com/registration/new) Model Context Protocol # Rinkta MCP: time tracking and invoicing for AI assistants Rinkta runs an authenticated MCP server that any compatible AI client can connect to — Claude, Cursor, ChatGPT, Cline, Zed. Once connected, your AI captures billable hours, answers questions about clients and projects, and generates invoices on your behalf without leaving the chat. [Get MCP access](https://app.rinkta.com/registration/new) Setup ## Three steps to AI-driven billing Pointing your AI client at the Rinkta MCP server takes a minute or two. OAuth handles the rest. ### Add the server Add https://app.rinkta.com/mcp as an MCP server in Claude Desktop, Cursor, ChatGPT, Cline, or any other compatible client. The transport is streamable-HTTP. ### Authorize via OAuth Your client opens a Rinkta sign-in flow. Approve the scopes you want — read workspace, write billing entries, generate invoices — and the connection is live. ### Talk to your AI Ask your AI to log work, summarize project hours, or draft this month's invoices. It calls Rinkta tools on your behalf and streams results back into the conversation. Capabilities ## What your AI can do once connected Rinkta's MCP server exposes a set of typed tools. Any MCP client can discover and call them — your AI does the work. ### Log billable hours Describe completed work in chat — "shipped the auth refactor for Acme yesterday" — and the AI estimates time and creates a billing entry against the right client. ### Query workspace state Ask for hours by client, project, or week. The AI calls the right tool and returns numbers from your live Rinkta data, never stale exports. ### Generate invoices Tell the AI to draft this month's invoices. It pulls billable entries, groups by client, applies your rates and tax settings, and creates drafts for review. ### Manage clients and projects Create new clients, set up projects, update rates — all through natural language. The AI calls Rinkta's create/update tools so you don't open the dashboard. ### Run profitability reports Ask for project profitability, utilization, or unbilled time. The AI runs the report and summarizes the numbers in plain language, with raw data on request. ### OAuth-scoped access Tools the AI can call are limited by the OAuth scopes you grant. Permissions follow your Rinkta role, and tokens are revocable in one click. Compatibility ## Works with any MCP client Rinkta MCP is a standard streamable-HTTP server. If your AI tool speaks the Model Context Protocol, Rinkta works with it. ### Claude Desktop Add Rinkta as an MCP server in Claude Desktop and use Claude as your billing assistant during the day. ### Cursor Connect from Cursor's MCP settings to log billable coding hours straight from your editor as you ship features. ### ChatGPT Use ChatGPT's MCP support to query Rinkta data and bill clients without leaving the chat tab. ### Cline VS Code extensions like Cline pick up the Rinkta MCP server and let you bill development work as it happens. ### Zed Configure Zed's assistant to talk to Rinkta and turn pair-programming sessions into billable entries automatically. ### Custom agents Rinkta exposes a vanilla MCP streamable-HTTP endpoint. Any MCP SDK (Python, TypeScript, Go, Rust) can connect over OAuth. FAQ ## Rinkta MCP FAQ How the Rinkta MCP server works, what it exposes, and how it stays secure.
What is the Rinkta MCP server? ◀ Rinkta runs an authenticated streamable-HTTP MCP server at https://app.rinkta.com/mcp. Any AI client that speaks the Model Context Protocol — Claude Desktop, Cursor, ChatGPT, Cline, Zed, or a custom agent — can connect to it. Once connected, your AI gains a set of tools for tracking time, querying workspace state, and generating invoices on your behalf.

Which AI clients work with Rinkta MCP? ◀ Any MCP-compatible client. Tested: Claude Desktop, Cursor, ChatGPT, Cline, Zed, Continue, and Windsurf. Because Rinkta uses the standard streamable-HTTP transport, custom agents and future clients work without code changes on our side.
---
How does authentication work? ◀ OAuth 2.0. When your AI client first connects to https://app.rinkta.com/mcp, it opens a Rinkta sign-in flow in your browser. Approve a scoped permission set and the client receives an access token. Tokens follow your Rinkta role — agencies can give individual team members different access levels — and revoke in one click.
---
Which Rinkta features are available through MCP? ◀ Logging billable entries, reading hours by client / project / period, listing and creating projects and clients, generating draft invoices, and running profitability reports. The full tool list is discoverable by any MCP client at runtime, so your AI sees the tools it can call as soon as it connects.
---
What plan do I need for MCP access? ◀ MCP agent access is included in the Agency plan ($299/mo billed yearly). Team and Studio plans cover the same data, just without the MCP server endpoint enabled.
---
Is this safe? What can my AI actually see? ◀ MCP is opt-in per call. Your AI can only call the tools allowed by your OAuth scopes — grant read-only access to hours, write access to entries, or both. Token revocation is one click in Rinkta settings, every tool call is logged to your audit trail, and Rinkta never trains AI models on your workspace data.
---
Can I use Rinkta MCP with a custom agent? ◀ Yes. The MCP server is a standard streamable-HTTP endpoint at https://app.rinkta.com/mcp. Any MCP SDK (Python, TypeScript, Go, Rust) can connect, complete the OAuth handshake, and call the tools — build daily standup summarizers, end-of-week invoice generators, on-call billing bots.
---
How is this different from the Rinkta API? ◀ The REST API is for programmatic clients you control — your scripts, your integrations. MCP is for AI agents you converse with. Same data, different access pattern: AI clients discover and call tools at conversation time without hard-coded endpoints, so your AI adapts as Rinkta gains new capabilities.
