# 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.
|
|
|
|
```bash
|
|
npm install -g @global-chat/mcp-server
|
|
```
|
|
|
|
Add to your MCP client configuration:
|
|
|
|
```json
|
|
{
|
|
"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](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](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
|

## Limitations
|
|
- Use this skill only when the task clearly matches the scope described above.
|
|
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
|
|
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
