Global Chat Agent Discovery

Overview

Global Chat is described by its contributed source as a cross-protocol agent discovery directory. Verify current service availability and coverage; directory totals and listings are not independently guaranteed. On 2026-10-14, the declared public source repository returned HTTP 404. Do not install a package or configure a host until its publisher, source, version and current service have been verified. 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 view @global-chat/mcp-server version repository dist.integrity
# Inspection only. After publisher/source verification, install a reviewed pinned version in an isolated project.

Add to your MCP client configuration:

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

The configuration is a template: replace REVIEWED_VERSION with a verified version and apply it only within authorized host setup. Discovery does not authorize installing or invoking a listed tool.

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, verify the current validator and its data policy:

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

The following responses are illustrative formats, not verified live results or endorsements. Check publisher identity, endpoint ownership, authentication, data retention and requested permissions for each candidate.

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 syntax against the relevant current protocol; validation does not guarantee 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: Inspect the verified pinned package and host error first. Do not run an unknown package merely to diagnose a connection.
