Global Chat Agent Discovery

Overview

Global Chat is a cross-protocol AI agent discovery platform that aggregates MCP servers and AI agents from 6+ registries into a single searchable directory. This skill helps you find the right MCP server, A2A agent, or agents.txt endpoint for any task by searching across 18,000+ indexed entries. It also provides an MCP server (@global-chat/mcp-server) for programmatic access to the directory from any MCP-compatible client.

When to Use This Skill

• Use when you need to find an MCP server for a specific capability (e.g., database access, file conversion, API integration)
• Use when evaluating which agent registries carry tools for your use case
• Use when you want to search across multiple protocols (MCP, A2A, agents.txt) simultaneously
• Use when setting up agent-to-agent communication and need to discover available endpoints

How It Works

Option 1: Use the MCP Server (Recommended for Agents)

Install the Global Chat MCP server to search the directory programmatically from Claude Code, Cursor, or any MCP client.

npm install -g @global-chat/mcp-server

Add to your MCP client configuration:

{
  "mcpServers": {
    "global-chat": {
      "command": "npx",
      "args": ["-y", "@global-chat/mcp-server"]
    }
  }
}

Then ask your agent to search for tools:

Search Global Chat for MCP servers that handle PostgreSQL database queries.

Option 2: Use the Web Directory

Browse the full directory at https://global-chat.io:

1. Visit the search page and enter your query
2. Filter by protocol (MCP, A2A, agents.txt)
3. Filter by registry source
4. View server details, capabilities, and installation instructions

Option 3: Validate Your agents.txt

If you maintain an agents.txt file, use the free validator:

1. Go to https://global-chat.io/validate
2. Enter your domain or paste your agents.txt content
3. Get instant feedback on format compliance and discoverability

Examples

Example 1: Find MCP Servers for a Task

You: "Find MCP servers that can convert PDF files to text"
Agent (via Global Chat MCP): Searching across 6 registries...
  - @anthropic/pdf-tools (mcpservers.org) — PDF parsing and text extraction
  - pdf-converter-mcp (mcp.so) — Convert PDF to text, markdown, or HTML
  - ...

Example 2: Discover A2A Agents

You: "What A2A agents are available for code review?"
Agent (via Global Chat MCP): Found 12 A2A agents for code review across 3 registries...

Example 3: Check Agent Protocol Coverage

You: "How many registries list tools for Kubernetes management?"
Agent (via Global Chat MCP): 4 registries carry Kubernetes-related agents (23 total entries)...

Best Practices

• Use the MCP server for automated workflows and agent-to-agent discovery
• Use the web directory for manual exploration and comparison
• Validate your agents.txt before publishing to ensure maximum discoverability
• Check multiple registries — coverage varies significantly by domain

Common Pitfalls

• Problem: Search returns too many results Solution: Add protocol or registry filters to narrow the scope

• Problem: MCP server not connecting Solution: Ensure npx is available and run npx -y @global-chat/mcp-server manually first to verify
