A visual harness builder for ai agents

A gateway + skill letting Claude Code agents collaborate across machines

One open A2A 1.0 mesh for Claude Code, Codex, Cursor, Cline, Continue and Gemini.

Zero-infrastructure A2A messaging between AI agents on different machines — Claude, ChatGPT/Codex, Copilot, any harness; ntfy relay transport, no ports, no server

AI agent for writing, research, code, DeFi & blockchain. Pay per task in USDC on Base or Solana. A2A + MCP + x402 protocols.

Neutral self-hosted registry and toolkit for Agentic Resource Discovery.

Agent-to-agent communication and multi-agent messaging, local-first: an A2A-inspired coordination platform where AI agents talk in natural language, manage tasks with human approval, and never send your data to the cloud. 65-command API, Python client, web UI, encrypted backups.

Go-first, knowledge-graph-grounded agent platform — built on toolnexus + ctx-optimize

Free CLI to scan AI-agent readiness (12/33 signals, MIT). Bad score? Get ready-to-install ZIP fix-pack with llms.txt, schema, A2A, MCP for $1/$29/$99 at agentfix.pro.

Open, experimental specification (v0.1) for machine-readable trust and Cognitive Passports for autonomous agents. A proposal, not a standard.

Machine-discoverable x402 micro-workers powered by Venice AI, paid in USDC, with A2A and MCP discovery.

Runnable Spring AI 2.0 demo — govern every LLM call, MCP tool call and agent-to-agent hop through the self-hosted Dvara control plane. Approval gates, PII blocking, hash-chained audit.

The agent that helps agents find other agents — MCP server, A2A card, OpenAPI for AgentSearch (agentsearch.luthersystems.com).

A2A Nexus — a control plane for delegating, tracking, and recovering work across agent nodes

Open discovery infrastructure for AI agents. Crawl, validate, normalize, and search A2A-compatible agents.

Compile a declarative DAG of subagents into a deployed, orchestrated team on AWS Bedrock AgentCore — agent manifests + dependency resolution → a provisioning plan and a topological supervisor.

Audit your A2A agent card across L1-L4 trust dimensions on every PR. GitHub Action wrapping @agentlair/a2a-trust-audit.

Repository for sample snippets of agents, covering a2a, langgraph, ollama setup, phoenix.
