vurb.ts

Overview

Vurb.ts is a comprehensive TypeScript framework for building production MCP servers that provides multiple approaches to implementation, from declarative YAML configuration to code-based solutions with presenters and FSM state gates. It features a typed layer between data and AI agents that strips undeclared fields, redacts PII, gates tools by workflow state, and deploys to various edge platforms. The framework supports Model-View-Agent architecture and includes advanced features like semantic routing, cache hints, and Zod validation.

FAQ

What is the difference between declarative YAML and code-based approaches in Vurb?

The declarative YAML approach allows you to define an entire MCP server in a single YAML file with no code or build steps. The code-based approach offers more flexibility with TypeScript, featuring Presenters for perception control and FSM State Gates for workflow-based tool visibility.

How does Vurb ensure data security and PII protection?

Vurb implements PII redaction through a 'Late Guillotine' approach that runs after UI logic, strips undeclared fields at RAM level, and allows rule-based governance that travels with the data rather than being hardcoded in system prompts.
