BLAH (Barely Logical Agent Host)

Open-source ecosystem for creating, testing, and sharing AI agent tools with a visual flow editor, simulation environmen...

Created byApr 23, 2025

PROJECT IN EXTREME POC MODE - NOTHING STABLE AT ALL - DOCS AND VISION ARE PURELY NOTES

BLAH - Barely Logical Agent Host - Update #1
(think npmjs for tools)
Once this list is fully done, the BLAH JSON schema will be finalized.
  • Tools - [x] Local functions - [x] Hosted functions - [ ] Registry - [ ] Publish - [ ] Browse - [x] Mcp support - [x] Local Stdio - [x] Local SSE - [ ] Hosted SSE - [x] Slop Support - [x] Local Slop - [x] Hosted Slop - [ ] Tool Composability - [ ] Grouping - [ ] Flows - [ ] Triggers / Tags - [ ] Extends - [x] Local blah.json - [ ] Hosted blah.json - [ ] Debugging - [ ] Playground - [ ] Logging
Notes:
  • The flows will be using a subset of agnt.gg's flow schema
  • Extend means you can compose blah.json's in any way you like. (think what if you just want to include a designers you follow tools)
  • The registry means we will have a convenient way to just push and pull functions (tools)

BLAH - Barely Logical Agent Host

BLAH is an open-source ecosystem for managing, distributing, and executing AI agent tools using the Model Context Protocol (MCP). It provides a decentralized registry for MCP servers that promotes transparency, security, and community-driven development.

Project Structure

This project is organized as a monorepo using Turborepo:
  • `packages/cli` - The main BLAH CLI tool for working with MCP
  • `apps/web` - Web interface for BLAH
  • `apps/docs` - Documentation site

Getting Started

Prerequisites

  • Node.js >= 18.18.0 (Node 20+ recommended)
  • pnpm

Installation

Quick Start with the CLI

See the [CLI README](packages/cli/README.md) for detailed instructions on using the BLAH CLI.

Currently working on

  • Need a way to debug mcp servers using any model/ide
  • Think about portals
  • lisa watts came up with "auton", likely what i am going to suggest
Unrelated Ideas
  • Need save state in ideas so you don't lose stuff (if you hadn't comitted)
  • upvotes for social tooling
  • automatic error rate
  • share your tool combination results

Using a local blah.json

Hosted blah.json (Valtown)

Getting started (hosted)

  1. Setup a Valtown account
  1. Create a new HTTP function named `blah`

Adding to your Client

  • Claude - Desktop - Code (CLI)
  • Cursor
  • Cline
  • Windsurf
  • BLAH Client
  • Are there any nice web clients yet

Development

I am still working on tools to make development not shit.

Logging

While developing this, I want to send logs from everybodies clients to just figure out all the fucking errors the clients are throwing due to different configures.

Playground

So far just a basic client that lists prompts, resources, and tools. Could be interactive later, and should also run against tests.

Needs improvement

  • Valtown is the current wrapper, need to be an alternative maybe using Vercel functions or some shit.
  • Need a nice strategy for composability

What is BLAH?

BLAH is an open-source ecosystem for managing, distributing, and executing AI agent tools using the Model Context Protocol (MCP). It provides a decentralized registry for MCP servers that doesn't suffer from misaligned incentives, promoting transparency, security, and community-driven development.
**Key Features:**
  • Open-source infrastructure that any system (IDE, AI platform, etc.) can connect to
  • Language-agnostic tool registry supporting unlimited tool selection
  • Robust security through optional signing and verification of MCP servers
  • Comprehensive CLI for publishing, discovering, and managing tools
  • Support for various tool types: functions, REST endpoints, local files, or standard manifests

Vision

BLAH aims to be the foundation for a new generation of AI tools that can be easily shared, discovered, and composed. We envision a future where:
  1. **Anyone** can create and share tools that extend AI capabilities
  1. **Everyone** has access to a rich ecosystem of tools regardless of their technical background
  1. **Every system** can integrate with this ecosystem through standard protocols

Getting Started

Installation

Basic Usage

Core Concepts

The Registry

BLAH's registry is designed with lessons learned from package managers like npm, focusing on:
  • **Transparency**: All infrastructure code is open-source
  • **Decentralization**: Storage options include local, cloud, IPFS, or gists
  • **Security**: Optional signing of MCP servers with verification
  • **Governance**: Community-driven with no single entity controlling the ecosystem

Agent Behavior

BLAH supports various agent interaction patterns:
  • Parallel execution
  • Recursive tool calls
  • Branching workflows
  • Sequential processing
  • Complex graph-based workflows

Tool Definition

A tool in BLAH is fundamentally a function, but can be represented as:
  • Code snippets
  • RESTful endpoints
  • Local executables
  • Standard manifests (SLOP, agents.json)
Every tool should explicitly document how it's invoked, though this isn't mandatory.

CLI Commands

BLAH comes with a comprehensive CLI:

Manifests

BLAH uses a manifest file (`blah.json`) to define tools and their dependencies. This manifest can exist:
  • In a project workspace
  • In the home directory
  • Hosted in the cloud
  • As a gist or on IPFS
Example `blah.json`:

Standards Support

BLAH supports and aims to be compatible with:
  • Model Context Protocol (MCP)
  • SLOP (Structure for Language Operator Protocols)
  • agents.json
  • [Your own custom protocols through converters]

Discovery and Metadata

Tools in BLAH are organized using:
  • Tags (e.g., #TOOLBELT)
  • Semantic metadata for intuitive navigation
  • Usage analytics for popularity-based recommendations
  • User-based recommendations (tools used by similar users)

Architecture

BLAH consists of three main components:
  1. **Registry**: For tool storage and discovery
  1. **CLI**: For interacting with the registry and managing tools
  1. **MCP Server**: For executing tools within agent workflows
Currently, [ValTown](https://www.val.town) serves as the primary backend for registry storage and compute, though alternative implementations are welcome.

Security & Accountability

BLAH takes security seriously:
  • Optional signing of MCP servers
  • Code execution in sandboxed environments
  • Comprehensive logging for accountability
  • Compliance with local laws and regulations

Roadmap

  • Host the MCP server on cloud platforms (e.g., Cloudflare Workers)
  • Create a web-based tool explorer and documentation site
  • Improve debugging and developer experience
  • Develop a tool creation wizard/generator
  • Implement tool recommendation system

Future Ideas

  • User behavior sharing for personalized tool recommendations
  • Scheduled agent execution through cron-like mechanisms
  • Decentralized governance model for registry management
  • Extension ecosystem for custom registry implementations
