Your agent builds it. MeroFoundry runs it.
Sign up for free. Connect your AI to MeroFoundry however you use it today: on the web, in your coding IDE, or the CLI. Let your agent build the database, business rules, auth, and UI, then publish instantly to your custom domain with its own built-in MCP server.
Quick start: register, then open your AI and tell it to connect tohttps://platform.merofoundry.com/mcp
From prompt to production
Your agent drives MeroFoundry over MCP. No boilerplate configuration, no wiring up AWS or auth providers.
Connect your agent
Add MeroFoundry's authoring MCP server to Claude Code, Claude Desktop, Cursor, or your terminal CLI in seconds.

Describe and build
Tell your agent what to build. It creates data models, field validations, relational queries, TypeScript business rules, and UI pages.

Publish with MCP built in
Deploy instantly to a live HTTPS custom domain. Your application automatically serves end-user pages and its own consumer MCP server.

Everything your agent needs to build real software
Not toy prototypes. MeroFoundry provisions production infrastructure backed by real databases, security scopes, and event engines, with the frontend and the backend in one place.
Data models that shape your API
Fields, relationships, and validation rules. When your agent changes the model, REST endpoints and OpenAPI specs update automatically.
Event-driven rules engine
Trigger actions on events. Run business logic before or after saves, validate responses, or run asynchronous background tasks.
Your app's own MCP server
Give your end users tools they can use through their own AI assistants. Scope catalog access through your application's permissions.
Tenant and workspace security
Built-in tenant isolation, user roles, and entitlements checked automatically by the platform with OAuth 2.1 and PKCE.
Vector search and AI workflows
Generate embeddings with your preferred provider, execute semantic similarity queries, and integrate LLMs into business rules.
TypeScript custom functions
Write TypeScript functions for advanced application logic. Transform data, query records, and call external APIs securely.
What runs where
MeroFoundry separates the authoring control plane, where AI agents create schemas, rules, and layouts, from the application runtime tier, which serves end-user pages, APIs, and consumer MCP requests.
Authoring control plane
- OAuth 2.1 and PKCE verification
- Scoped application tokens
- Mutation idempotency engine
- Tool dispatcher and rate limiter
Schema and records
- Versioned model schemas
- Validated JSON records
- Generated REST and OpenAPI
Rules and WASM functions
- TypeScript compiled to WebAssembly
- Event-triggered rules
- Outbound integrations
Published application runtime
- Public web UI on a custom domain with TLS
- REST API v1 with scoped API keys
- The app's own MCP server, RBAC enforced

Questions people actually ask
Do I need a credit card to start?
No. Hobby is free and does not ask for one.
Can I use my own domain?
Yes, on every plan including Hobby. Every application also gets a URL on merofoundry.app the moment it is published, so you can share it before you point a domain at it.
Can my app send email?
Yes, through your own provider. You connect your own SMTP or sending service, such as SendGrid, and mail goes out under your domain and your reputation. We do not send it for you and we do not resell it.
What do the AI features cost?
Nothing extra from us. You connect your own AI provider account and credentials, and you pay that provider directly at their rates. We do not resell model calls or mark them up.
