Allows deployment and management of APIs on Kubernetes clusters, including staging and production environments, scaling, and monitoring.
Provides tools for creating and managing Neo4j graph databases, including nodes, relationships, queries, and full-text search.
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., "@RationalBloks MCP Server deploy my task manager API to production"
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.
Deploy production APIs in minutes. 49 tools for projects, schemas, deployments, object storage, and graph data — delivered on infrastructure you own (self-host or your own BYOC cluster).
RationalBloks MCP lets AI agents (Claude, Cursor, etc.) deploy production APIs from a JSON schema. No backend code to write. No infrastructure to manage.
