The protocol-agnosticinfrastructure layerfor AI tool interoperability

THE AI TOOLS FRAGMENTATION PROBLEM

The AI ecosystem has reached a critical inflection point characterized byprotocol fragmentation. Tools are siloed across incompatible interfaces like MCP and SLOP, each with their own schemas, transport layers, and execution contexts.

This technical fragmentation creates increasing implementation overhead for developers, reducing tool adoption and impeding innovation.

What if we could create a decentralized infrastructure layer with bidirectional protocol adapters, a standardized tool registry, and visual composition primitives? A system where tools could be written once and deployed everywhere?

This is the core technical challenge BLAH solves —
a unified abstraction layer for true tool interoperability.

OUR VISION

UNIVERSAL PROTOCOL BRIDGE

Implements bi-directional adapters between Model Context Protocol (MCP), Simple Language and Object Protocol (SLOP), and other emerging interfaces with efficient transport-agnostic message passing.

DECENTRALIZED REGISTRY

Distributed versioned tool repository with hierarchical dependency resolution, semantic versioning support, and configurable provider execution strategies with built-in fallback mechanisms.

2

VISUAL FLOW COMPOSITION

Declarative, graph-based workflow engine with conditional branching logic, dynamic parameter binding, and compile-time transformation into standalone executable tools.

CHALLENGES & SOLUTIONS

TECHNICAL CHALLENGES

  • ✕

    Protocol Incompatibility

    Heterogeneous schemas, transports, and execution contexts create implementation silos

  • ✕

    Centralized Registries

    Single-provider architectures create bottlenecks and vendor lock-in

  • ✕

    Limited Composability

    No unified abstraction for chaining tool calls with conditional logic

  • ✕

    Distributed Discovery

    No standardized protocol for tool indexing and querying

  • ✕

    Implementation Overhead

    Creating cross-protocol tools requires redundant implementations

PROTOCOL BRIDGING LAYER

BLAH implements an adapter layer with bidirectional transformations between protocol-specific schemas. This allows seamless interoperability between MCP's JSON-RPC-based communication, SLOP's RESTful API patterns, and other tool interface standards without protocol-specific code duplication.

DAG-BASED FLOW ENGINE

Implements a directed acyclic graph (DAG) processing system that enables sophisticated tool composition. Flows are defined declaratively, compiled into executable tool representations, and executed with conditional branching based on parameter evaluation.

DISTRIBUTED TOOL REGISTRY

A decentralized repository architecture that enables transparent tool distribution across providers. Implements semantic versioning with dependency resolution, multi-provider registration, and validation against standardized schemas.

MULTI-TRANSPORT EXECUTION

BLAH abstracts the transport layer, supporting STDIO for CLI-based communication, Server-Sent Events (SSE) for web integrations, and extensible provider architecture for cloud-based execution on platforms like ValTown. All methods expose a unified API regardless of the underlying transport mechanism.

SYSTEM COMPONENTS

CORE CLI & PROTOCOL STACK

The core infrastructure layer with the following components:

  • McpServer implementation with StdioServerTransport and JSON-RPC messaging
  • SLOP protocol adapter with API endpoint integration
  • ReactFlow-based visual workflow editor and compiler
  • Configuration inheritance system with deep merge capabilities
  • Transport-agnostic execution layer (STDIO/SSE/HTTP)
bash
1# Start MCP server with STDIO transport
2blah mcp start
3
4# Start server with SSE transport on port 4200
5blah mcp start --sse --port 4200

WEB ECOSYSTEM

The distributed web-based components that extend the core infrastructure:

  • Registry: PostgreSQL-backed versioned tool repository
  • Playground: Monaco-powered blah.json editor & test environment
  • Documentation: Comprehensive schema references & guides
  • Dashboard: Tool management & analytics interface

These distributed components communicate via standardized APIs to create a coherent ecosystem for AI tool development, testing, and distribution.

ENGINEERING IMPERATIVE

We're witnessing the early formation of protocol silos in the AI ecosystem. As tool-using models become increasingly central to AI architectures, the fragmentation between MCP, SLOP, and proprietary tool systems threatens to create significant technical debt for developers implementing cross-platform tool functionality.

BLAH provides the critical abstraction layer that decouples tool semantics from protocol specifics, much like how TCP/IP abstracted network communication from physical transport layers. This standardized infrastructure enables a robust, interoperable tool ecosystem without requiring protocol-specific implementations.

A unified protocol bridge is essential infrastructure for the emerging AI tool ecosystem.
