Universal Connector Catalog
One SDK to connect PostgreSQL, MySQL, SQL Server, SAP, Zoho, REST APIs, gRPC services, and more. Community-built connectors included.
HostMCP.dev is the enterprise MCP enablement suite that turns your databases, APIs, ERPs, and microservices into AI-callable tools — with full audit trails, compliance controls, and regional data residency.

}From zero to production-ready MCP tools in minutes, not months.
One SDK to connect PostgreSQL, MySQL, SQL Server, SAP, Zoho, REST APIs, gRPC services, and more. Community-built connectors included.
Auto-generate MCP tool definitions from OpenAPI specs. Drag-and-drop join builder for multi-table queries. No code required.
Run real tool calls against your connectors, preview JSON schemas, and validate outputs before deploying to production.
Upload or paste any OpenAPI 3.x spec. Our engine auto-parses endpoints, parameters, and responses into fully typed MCP tool schemas.
Every action is logged and immutable. GDPR, India DPDP Act, PCI-DSS, and HIPAA audit trail built in — not bolted on.
Enterprise teams can deploy MCP servers in their own GCP region — EU, APAC, US — for data sovereignty and low-latency compliance.
Community-maintained connectors for the systems you already use.

Pick a connector from the catalog — database, REST API, ERP, or custom process. Enter credentials securely. We auto-scan the schema.
Select tables, endpoints, or processes. Name your MCP tools, write natural-language descriptions, and let the engine generate JSON schemas.
One-click publish to your MCP server. Your AI assistants (Claude, GPT, Gemini) can now discover and call your tools via the MCP protocol.
MCP only manages tool metadata — not your actual business data. But we still treat it with enterprise-grade care: credentials are encrypted, audit logs are immutable, and enterprise customers can pin their MCP registry to a GCP region of their choice for data residency compliance (GDPR, DPDP, HIPAA).
