Hatchable

MCP Registry License: MIT

Build and host full-stack web apps and sites on Hatchable from any MCP client. Every project gets its own Postgres database, auth, storage, domains, cron and email, plus a live URL in seconds. Free tier, no credits.

This repo is two things: the Claude Code plugin for Hatchable (this directory is the plugin), and the connector notes for every other MCP client. Hatchable's code runs on our infrastructure, not yours; there is nothing to build or install locally.

Endpoint	https://hatchable.com/mcp
Transport	Streamable HTTP (MCP 2025-03-26)
Authentication	OAuth 2.1 with PKCE and Dynamic Client Registration (RFC 7591). Bearer fallback.
Registry	com.hatchable/hatchable
Homepage	hatchable.com
Docs	hatchable.com/docs/developers

Claude Code plugin

/plugin marketplace add anthropics/claude-plugins-community
/plugin install hatchable@claude-community

Then connect your account: run /mcp, pick hatchable, and complete the sign-in. New accounts are free, and the first app you publish to the open web is free too.

What the plugin adds:

• The Hatchable MCP server, preconfigured. 34 tools for creating projects, writing files, running SQL, deploying, reading logs, and forking templates. Full reference at hatchable.com/docs/developers/mcp.
• /hatchable:new <description>: build and deploy an app from a plain-language description. Returns a live URL.
• /hatchable:import: deploy the repo you are sitting in. Maps your files to the platform structure, runs the validators, and walks any blockers.
• /hatchable:fix <what's wrong>: diagnose a rejected deploy or a broken live app using the platform's own logs and dry-run validators.
• The hatchable:builder agent: an app builder Claude can delegate whole build tasks to. It creates, codes, deploys and verifies in the cloud, then hands back the live URL. Mention it with @hatchable:builder or let Claude pick it.

A Hatchable project is a folder: paths become routes, SQL files become schema, one TOML file declares the rest. The platform serves its own build patterns to your agent over MCP (list_skills, read_skill), so Claude reads the current conventions at build time instead of relying on training data.

To try the plugin from a checkout before installing it: claude --plugin-dir . in this directory.

Setup by client

Claude Code (terminal)

Install the plugin (see above), or add the server directly. OAuth handles the rest:

claude mcp add --transport http hatchable https://hatchable.com/mcp

Claude.ai (web)

1. Open claude.ai/customize/connectors and click the + next to Connectors.
2. In the Add custom connector dialog, name it Hatchable, paste https://hatchable.com/mcp, and click Add.
3. Claude redirects you to hatchable.com to approve — that creates your free account.

Works on Free (1 connector), Pro, Max, Team, and Enterprise. On Team/Enterprise, an owner adds it from Organization settings → Connectors.

ChatGPT

1. Open chatgpt.com/apps#settings/Connectors/Advanced, toggle on Developer Mode, and click Create app.
2. Name it Hatchable, paste https://hatchable.com/mcp under MCP Server URL, keep OAuth, tick the consent box, and click Create.
3. ChatGPT redirects you to hatchable.com to approve — that creates your free account.

Requires a Plus, Pro, Business, Enterprise, or Edu plan (Developer Mode prerequisite).

Codex

1. Open Codex → Settings → MCP servers → + Add server.
2. Name it Hatchable, pick Streamable HTTP, paste https://hatchable.com/mcp, and Save.
3. Click Authenticate on the new row and approve the popup on hatchable.com — that creates your free account.

Google Antigravity

1. Open the Command Palette (Cmd/Ctrl + Shift + P).

2. Select Antigravity: Manage MCP Servers, then click View raw config.

3. Paste and save:

   {
     "mcpServers": {
       "hatchable": {
         "serverUrl": "https://hatchable.com/mcp"
       }
     }
   }
   

4. Reopen Manage MCP Servers, click Authenticate on the hatchable row, and approve on hatchable.com.

Other MCP clients

Any client that supports Streamable HTTP + OAuth will work. Configure https://hatchable.com/mcp as the endpoint and let the client handle the OAuth dance. Clients that only support bearer tokens should send Authorization: Bearer <API_KEY>, where the key comes from the console.

What you can do (tool surface)

34 tools, served live by the endpoint:

• Project lifecycle: create_project, get_project, list_projects, update_project, fork_project, create_preview_link
• Files: write_file, write_files, patch_file, read_file, grep, list_files, delete_file, upload_file, list_pending_uploads, import_file_from_url
• Database: execute_sql, get_schema
• Deploy and observability: dry_run_deploy, deploy, list_deployments, get_deployment, list_functions, run_function, run_code, view_logs, list_cron_jobs
• Agent tasks: list_agent_tasks, update_agent_task (plain-language requests the project owner files in the console)
• Guidance and discovery: list_skills, read_skill, search_documentation, search_projects, submit_platform_feedback

Each project ships with a dedicated Postgres database, built-in auth (email code and OAuth providers), cron scheduling, object storage, email sending and AI routing, all reached through the hatchable SDK inside your handlers. No npm install, no build step. See hatchable.com/docs/developers for the SDK and handler contract.

Manifests

• server.json — MCP Registry manifest (schema version 2025-12-11), also served at hatchable.com/server.json and hatchable.com/.well-known/mcp/server.json.
• smithery.yaml — Smithery submission config.

Security and auth

• OAuth metadata (RFC 8414): /.well-known/oauth-authorization-server
• Protected-resource metadata (RFC 9728): /.well-known/oauth-protected-resource
• Dynamic Client Registration (RFC 7591) is supported — MCP clients can register themselves automatically.

Bearer tokens are scoped per-account. You can rotate or revoke them in the console.

Docker (for registries and scanners)

The Dockerfile in this repo is a small stdio-to-HTTP proxy (proxy.mjs). It exists so registries and quality scanners that expect a runnable container (Glama, Smithery, etc.) can introspect the tool surface. End users don't need to build it — configure https://hatchable.com/mcp directly in your MCP client and let the client's native HTTP transport talk to the server.

docker build -t hatchable-mcp .
docker run --rm -i hatchable-mcp  # stdio ↔ https://hatchable.com/mcp
