Discover AI Agents Across Registries

Global Chat Agent Discovery aggregates MCP servers and AI agents from 6+ registries into a single searchable directory of 18,000+ indexed entries. It provides both a web interface and an MCP server (@global-chat/mcp-server) for programmatic access, enabling you to search across multiple protocols (MCP, A2A, agents.txt) simultaneously to find the right tool for any task.

Use this skill when you need to find an MCP server for a specific capability like database access, file conversion, or API integration. Use it when evaluating which agent registries carry tools for your use case, or when setting up agent-to-agent communication and need to discover available endpoints. Use it to search across multiple protocols simultaneously rather than checking each registry individually.

Do NOT use this as a substitute for environment-specific validation or testing of the agents you discover. Do NOT treat search results as verified or production-ready without your own evaluation.

You provide search queries describing the capability you need (e.g., "PostgreSQL database queries", "PDF file conversion", "code review"). You can filter by protocol type (MCP, A2A, agents.txt) or registry source. You receive a list of matching servers or agents with details about their capabilities, source registries, and installation instructions.

For agents.txt validation, you provide your domain or paste your agents.txt content and receive instant feedback on format compliance and discoverability.

The MCP server integrates with any MCP-compatible client. Specifically documented:

• Claude - MCP client support for agent discovery
• Cursor - MCP client support for agent discovery
• Codex - MCP client support for agent discovery

Install the MCP server globally:

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 query from your agent:

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

The web directory is available at https://global-chat.io for manual browsing, and the validator at https://global-chat.io/validate for agents.txt compliance checking.

Developers building AI agent workflows who need to discover and evaluate MCP servers across multiple registries. Agent platform maintainers who want to validate their agents.txt files for maximum discoverability. Teams setting up agent-to-agent communication who need to find compatible endpoints across different protocols. Anyone comparing agent registry coverage for specific domains like Kubernetes management, database tools, or file processing.

Use the MCP server for automated workflows and agent-to-agent discovery. Use the web directory for manual exploration and comparison. Check multiple registries since coverage varies significantly by domain.
