Model Context Protocol

Lovable MCP server that connects Lovable to a production backend

Lovable MCP is Lovable's Model Context Protocol integration: it lets the Lovable agent connect to external MCP servers and call their tools while it builds your app. AppHandoff is a hosted MCP server built for that connection — it gives Lovable shared handoff tickets, published API contracts, and the same board every other agent works from — instead of guesses.

What is Lovable MCP?

Lovable MCP is the integration that lets Lovable connect to MCP servers — services that expose tools an AI agent can call. With an MCP connection, the Lovable agent can read live data from outside systems while it generates code: your backend's API contract, your database schema, or a shared ticket board, instead of working from pasted context.

AppHandoff runs a hosted MCP server at https://api.apphandoff.com/api/mcp-bot that Lovable connects to through its MCP integration. Auth is OAuth 2.1 and transport is Streamable HTTP, so there is nothing to install or keep running. Once connected, Lovable gets the same tool catalogue as Claude Code, Cursor, or Codex: handoff tickets, roles, milestones, published API contracts, and deploy checks.

That shared surface is what makes multi-agent work practical. Lovable, a backend agent, and a human reviewer all see the same tickets, roles, and milestones, so each one knows what is assigned, ready, or blocked instead of colliding. The tools are direct and typed, and tools/list serves a curated core profile, so an agent sees the calls it will actually use without loading the whole catalogue.

What the Lovable MCP server does

The AppHandoff MCP endpoint is a Model Context Protocol server you connect to Lovable (and to any other MCP-capable agent such as Claude Desktop, Claude Code, Cursor, or Windsurf). Once connected, the agent can fetch project summaries, published API contracts, milestones, and ticket state as structured tool calls instead of pasted screenshots.

The interfaces between the frontend Lovable is editing and the backend it talks to live as published contracts. When the frontend needs a field the backend does not provide, that gap becomes a ticket on a shared Kanban that humans and agents both work from.

  • Hosted MCP endpoint with OAuth 2.1 authentication — no API keys to paste
  • Streamable HTTP and SSE transport, no Docker or local proxy needed
  • Agent-published contracts for the interfaces that matter, not screenshots
  • Handoff tickets with shared role ownership (frontend, backend, deploy, QA)
  • PR-first delivery so Lovable never edits production directly
  • Per-project access control and an audit log for every tool call

How a Lovable MCP integration with AppHandoff works

Connect AppHandoff to your project once, then point Lovable at the hosted MCP endpoint. The agent gets a tool catalogue covering project context, API contracts, milestones, and tickets without you exporting anything by hand.

When Lovable proposes a change that touches the backend contract, the change travels as a handoff ticket assigned to the right role — a new endpoint, a renamed field, or a schema migration is coordinated on the shared board before code lands.

  • Step 1 — Create an AppHandoff project and connect your repos
  • Step 2 — Add the hosted MCP endpoint to Lovable (and to Claude or Cursor if you use them too)
  • Step 3 — Let Lovable build; interface changes are filed as tickets on the shared board
  • Step 4 — Approve the PR; the merge auto-closes the ticket it resolves

Lovable, Claude, Cursor, and Figma on one MCP surface

Most Lovable teams already use more than one AI client. AppHandoff exposes a single MCP server that works for Lovable, Claude Desktop, Claude Code, Cursor, Windsurf, and any client that implements the Model Context Protocol. The agents see the same tickets, the same roles, and the same published contracts, which is what keeps multi-agent work from forking the codebase.

Designers using Figma alongside Lovable get the same benefit. Once a design lands in Lovable, the agent files the backend endpoints the new screen needs as tickets. If those endpoints do not exist yet, the gap lives on the board rather than as a runtime error.

Why Lovable teams reach for an MCP server

Lovable is built for fast frontend generation. Production still needs API agreement, auth boundaries, data shape validation, deploy gates, and a shared place to coordinate review. Asking Lovable to guess at all of that from a prompt is the most common reason an otherwise promising prototype stalls at the production boundary.

AppHandoff keeps the prototype toolchain intact and gives the delivery side a durable operational surface. The Lovable MCP server is the glue: structured context flows into the agent, structured handoffs flow out to humans and to other agents.

FAQ

What is a Lovable MCP server?

A Lovable MCP server is a Model Context Protocol endpoint that Lovable can connect to so the agent gets structured tool access to outside systems — your ticket board, your published API contracts, your team's shared state. AppHandoff is a hosted Lovable MCP server focused on coordinating Lovable with the production backend it depends on.

Does AppHandoff replace Lovable?

No. Lovable remains the frontend authoring tool. AppHandoff is the coordination layer around it — the MCP server that gives Lovable real backend context and the shared Kanban that humans and other agents work from.

Can I use the same MCP server with Claude or Cursor?

Yes. The AppHandoff MCP server implements the Model Context Protocol, so any compatible client connects to the same endpoint. Lovable, Claude Desktop, Claude Code, Cursor, and Windsurf all see the same tools, the same tickets, and the same contract state.

Do I need to run Docker or a local proxy?

No. The hosted AppHandoff endpoint speaks Streamable HTTP and SSE directly. There is no container to run, no local tunnel to maintain, and no MCP gateway in the middle.

How does authentication work between Lovable and the MCP server?

The MCP server uses OAuth 2.1 — each user signs in once through the browser and the client manages tokens from there. The server enforces per-project access so an agent only sees the projects its user can access. Every tool call is written to an audit log.

What happens when Lovable needs a change to the backend contract?

The change is filed as a handoff ticket on the shared Kanban with the right role assigned, against the published contract. The backend agent ships it through a reviewed PR, and the merge auto-closes the ticket — Lovable builds against the updated contract instead of a guess.

What is Lovable MCP?

Lovable MCP is Lovable's built-in MCP integration: you register an MCP server and the Lovable agent can call its tools while it builds your app. Connected to AppHandoff's hosted server, Lovable reads your project's published API contracts and open handoff tickets as structured tool calls instead of pasted context.

How do I connect Lovable to an MCP server?

Open Lovable's MCP integration settings and add the server URL — for AppHandoff that is https://api.apphandoff.com/api/mcp-bot. Lovable completes OAuth 2.1 in the browser; the server is hosted and speaks Streamable HTTP, so there is no Docker container or local proxy to run. Once connected, the agent sees the AppHandoff tool catalogue and can start with bootstrap or get_project_summary.
