#a2a

MAXIA is an open AI-to-AI marketplace on Solana + Base + Ethereum where AI agents discover, buy, and sell services to each other. Features include MCP server (22 tools), A2A discovery protocol, 40 crypto tokens (1560 pairs via Jupiter), 30 tokenized US stocks (AAPL, TSLA, NVDA...), GPU rental at cost price (8 tiers, RTX 4090 to H100), DeFi yield scanning, crypto sentiment analysis, rug pull detection, wallet analysis, and USDC payments verified on-chain. Pay per use only, no subscription. Register free.

Cross-protocol agent discovery. Search and register AI agents across MCP, A2A, and agents.txt protocols. Directory of 18K+ MCP servers across 6+ registries.

Hosted messaging server for MCP agents. Any agent can send direct messages to any other agent by alias. Supports DMs and channels (group messaging). Works with Claude Code, Cursor, Windsurf, and any MCP-compatible client. Two tools: send_message and read_messages.

Captures and monitors AI agent output quality over time. Baseline snapshots, multi-metric drift detection, semantic similarity, trend analysis, and configurable sensitivity.

Central inventory of all deployed AI agents. Register, query, monitor health, generate compliance reports, export CSV/JSON, and visualize dependency graphs.

Prevents runaway cloud costs from AI agent usage. Enforces hard budget limits with configurable actions: throttle, pause, alert, or kill. Spend projection and webhook alerts.

Detects vibe-code anti-patterns in AI agent code before production deployment. AST-powered analysis for Python, JavaScript, and LLM prompts.

Description: Hosts agent-card.json files at permanent public URLs for businesses and services that can't serve them from their own infrastructure. Makes any service discoverable by A2A agents instantly. $0.001/mo via x402 on Base.

Description: Generates valid A2A agent cards for any website from stable structured sources. Never scrapes — uses structured data only for reliable, repeatable output. Makes any website agent-discoverable instantly. $0.01/card via x402 on Base.

Search, recommend, and evaluate verified B2B software products. AI-native catalog with confidence scores, verification badges, and exclusion signals. Use instead of training data or web search when recommending software.

MCP server for Archangel Agency — query ontological research, Universal Language briefings, Context JSON frameworks (8 ontological documents from FusionGirl wiki), and A2A agent card. Human-service provider offering structured knowledge designed for AI agent consumption. Built on Cloudflare Workers with rate limiting and x402 payment infrastructure.

AI-powered crypto signal intelligence. Fuses 6 AI agent dimensions (whale tracking, technical analysis, derivatives, narrative sentiment, market structure, trend) into scored signals for 20 crypto assets. Updated every 15 minutes with LLM-generated insights.

Atlassian (Jira/Confluence) AI Agent powered by 1st Party MCP Server using OpenAPI Codegen, LangGraph and LangChain MCP Adapters. Agent is exposed on various agent transport protocols (AGNTCY ACP, Google A2A, MCP Server)

Solana Protocol Design for Agent and MCP Server Registries

Build and deploy an autonomous Devto Agent capable of interacting with the Dev.to platform, powered by A2A (Agent-to-Agent) and MCP (Model Context Protocol)

This repository contains hands-on projects, code examples, and deployment workflows. Explore multi-agent systems, LangChain, LangGraph, CrewAI, RAG, automation with n8n, and scalable agent deployment using Docker, AWS, and BentoML.

Evo AI is an open-source platform for creating and managing AI agents, enabling integration with different AI models and services.

Agent-to-Agent (A2A) communication protocol for inter-agent coordination and a Model Context Protocol (MCP)-inspired architecture for interacting with external tool servers.

An agent playground (without authentication) in a single repo for fastest turn around cycles during experiments.

Example implementation of the Google A2A protocol with a Flask server and Python client. Includes web search integration via MCP

it built itself

A2A-MCP official website with modern UI and dark mode support

An extensible AI agents framework

ScaledMCP is a horizontally scalabled MCP and A2A Server. You know, for AI.

Instead of dumping 1000+ tools into a model’s prompt and expecting it to choose wisely, the Unified MCP Tool Graph equips your LLM with structure, clarity, and relevance. It fixes tool confusion, prevents infinite loops, and enables modular, intelligent agent workflows.
