As answered by people managing ExtendsClass JSON Generator and MCPForge.tech.
MCPForge.tech's answer:
Most MCP tools focus on generating servers.
MCPForge focuses on production deployment.
Beyond OpenAPI-to-MCP generation, MCPForge helps teams manage permissions, approvals, audit logs, security reviews, and governance controls required for real-world MCP deployments.
The goal is not just to create MCP servers, but to make them safe and manageable in production environments.
MCPForge.tech's answer:
MCPForge combines MCP generation, hosting, security, and governance in a single platform.
Instead of manually building, deploying, securing, and maintaining MCP servers, teams can import an OpenAPI specification and manage the entire lifecycle from one place.
It is designed for developers who want to move quickly without sacrificing visibility, permissions, and operational control.
MCPForge.tech's answer:
MCPForge is built for AI developers, agent builders, SaaS companies, API providers, automation engineers, and platform teams that want to expose APIs to AI agents through MCP.
It is particularly useful for organizations that already maintain OpenAPI specifications and want a faster path to production-ready MCP deployments.
MCPForge.tech's answer:
Next.js, React, TypeScript, Node.js, PostgreSQL, Prisma, Stripe, OpenAPI, MCP (Model Context Protocol)
MCPForge.tech's answer:
MCPForge started from a simple frustration. While experimenting with MCP, I noticed that most APIs already had OpenAPI specifications, yet exposing them to AI agents still required building and maintaining MCP servers manually. After repeating the same process multiple times, I decided to build a platform that could automate the process and eventually solve the operational challenges around security, permissions, approvals, and governance.
MCPForge.tech's answer:
No public customers yet. MCPForge is currently in its early stages and working with early adopters and developers, evaluating the MCP infrastructure.
