Roadmap
What’s shipping next.
A public view of what we’re building next and what developers can already use — tunnels, MCP, webhook tooling, and guides.
Priorities may change. Quarters are targets, not commitments.

Already available
Developer-facing surfaces you can use today.
TCP tunnel
Expose raw TCP services through Mercur with public host:port targets and connection metrics in the console.
WebSocket tunnel
Forward WebSocket connections over a public HTTPS URL so local WS services stay reachable during development.
Remote MCP
Let an IDE agent list endpoints, search HTTP request history, and open full payloads via Mercur’s remote MCP server.
Webhook tester
Try a public webhook URL without an account. Incoming requests appear in the browser; register to unlock Endpoints.
Docs & Guides
Quickstarts, security notes, troubleshooting, and step-by-step guides for webhook debugging and MCP setup.

Roadmap questions
How often is this roadmap updated?
We update it when priorities or ship status change. It is a living page, not a fixed annual plan.
Are the quarters commitments?
No. Quarters are planning targets. Features can move earlier or later as we learn from usage and feedback.
Where can I try what’s already shipped?
Use Docs and Guides for setup, open the webhook tester without an account, or create an account for Endpoints, TCP/WS tunnels, and remote MCP.
