}From legacy API to MCP tool in minutes
No code changes to your existing API. No custom server to maintain.
Connect your API
Paste your API base URL and add authentication (API key, Bearer token, OAuth 2.0, Basic Auth, and more). We support REST, SOAP, and GraphQL.
AI discovers your endpoints
Our AI reads your OpenAPI spec or crawls your API to identify every endpoint, its parameters, and what it does. Discovery takes seconds.
Deploy your MCP registry
Choose which endpoints to expose as MCP tools, copy your unique MCP URL, and drop it into Claude Code, VS Code, or any MCP-compatible client.
Everything you need to bridge the gap
Built for developers who need their existing APIs working with modern AI tooling — without months of refactoring.
Enterprise-grade security
API credentials encrypted at rest with AES-256-GCM. MFA, Passkeys, and U2F supported. Your secrets never leave our encrypted store.
Any protocol
REST, SOAP, and GraphQL supported. OpenAPI/Swagger spec import for instant discovery, or let our crawler map your API automatically.
AI-powered discovery
GPT-5-nano analyzes your endpoints and generates meaningful MCP tool names, descriptions, and input schemas automatically.
Granular permissions
Choose exactly which endpoints to expose as MCP tools. Customers can enable or disable individual tools without re-discovery.
Config generator
One-click config file generation for Claude Code, VS Code Copilot, OpenAI projects, and other MCP-compatible clients.
Force re-discovery
API added new endpoints? Hit re-discover and we re-crawl your API, adding new tools while preserving your existing configuration.
Team access
Pro and Enterprise plans include multi-user tenancies with role-based access (Owner, Admin, Member) and full audit logs.
Usage & billing
Real-time usage dashboards, per-registry breakdowns, invoice history, and one-time top-up purchases when you need more headroom.
