Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@MCP Server Templateslist available templates"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
MCP Server Templates
Production-grade MCP server starter templates with permission boundaries, integration tests, and eval contracts.
Templates
Template | Description | Key Features |
Minimal MCP server | Echo + calculate tools, Zod validation | |
Read-only database access | SQL validation, schema introspection, permission boundaries | |
External API proxy | Rate limiting, credential scoping, endpoint configuration |

Quick Start
Clone this repo or use "Use this template" on GitHub
Navigate to the template you want:
cd templates/basicInstall dependencies:
pnpm installStart the server:
pnpm start
Architecture
Each template follows the same patterns:
Permission engine — Declarative rules (allow/deny) evaluated before every tool invocation
In-memory test client — Integration tests via MCP SDK's InMemoryTransport
Eval contracts — YAML eval specs compatible with @visystems/claude-eval-runner
Shared Utilities
The shared/ directory contains reusable utilities:
permissions/— Permission policy types, engine, and PermissionDeniedErrortesting/— In-memory MCP test client for integration testserrors/— Typed error classes
Development
pnpm install
pnpm typecheck # TypeScript type checking
pnpm test # Run all tests
pnpm test:shared # Run shared utility tests only
pnpm test:basic # Run basic template tests onlyLicense

Create, deploy, and operate MCP servers directly from your GitHub repositories.
The OpenZeppelin Cairo Contracts MCP server generates secure smart contracts in the Cairo language for Starknet environments based on OpenZeppelin templates. It brings OpenZeppelin's proven security and style rules directly into AI-driven development workflows to create safe, production-ready contracts. Key capabilities include providing templates for ERC-20, ERC-721, ERC-1155, Multisig, Governor, and Vesting contracts.
Build multi-tenant apps over MCP. Schemas, CRUD, deploys — access control enforced server-side.
