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.\n\n## When to Use This Skill\n\n- Use when you need to find an MCP server for a specific capability (e.g., database access, file conversion, API integration)\n- Use when evaluating which agent registries carry tools for your use case\n- Use when you want to search across multiple protocols (MCP, A2A, agents.txt) simultaneously\n- Use when setting up agent-to-agent communication and need to discover available endpoints\n\n## How It Works\n\n### Option 1: Use the MCP Server (Recommended for Agents)\n\nInstall the Global Chat MCP server to search the directory programmatically from Claude Code, Cursor, or any MCP client.\n\n```bash\nnpm install -g @global-chat/mcp-server\n```\n\nAdd to your MCP client configuration:\n\n```json\n{\n  \"mcpServers\": {\n    \"global-chat\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"@global-chat/mcp-server\"]\n    }\n  }\n}\n```\n\nThen ask your agent to search for tools:\n\n```\nSearch Global Chat for MCP servers that handle PostgreSQL database queries.\n```\n\n### Option 2: Use the Web Directory\n\nBrowse the full directory at [https://global-chat.io](https://global-chat.io):\n\n1. Visit the search page and enter your query\n2. Filter by protocol (MCP, A2A, agents.txt)\n3. Filter by registry source\n4. View server details, capabilities, and installation instructions\n\n### Option 3: Validate Your agents.txt\n\nIf you maintain an `agents.txt` file, use the free validator:\n\n1. Go to [https://global-chat.io/validate](https://global-chat.io/validate)\n2. Enter your domain or paste your agents.txt content\n3. Get instant feedback on format compliance and discoverability\n\n## Examples\n\n### Example 1: Find MCP Servers for a Task\n\n```\nYou: \"Find MCP servers that can convert PDF files to text\"\nAgent (via Global Chat MCP): Searching across 6 registries...\n  - @anthropic/pdf-tools (mcpservers.org) — PDF parsing and text extraction\n  - pdf-converter-mcp (mcp.so) — Convert PDF to text, markdown, or HTML\n  - ...\n```\n\n### Example 2: Discover A2A Agents\n\n```\nYou: \"What A2A agents are available for code review?\"\nAgent (via Global Chat MCP): Found 12 A2A agents for code review across 3 registries...\n```\n\n### Example 3: Check Agent Protocol Coverage\n\n```\nYou: \"How many registries list tools for Kubernetes management?\"\nAgent (via Global Chat MCP): 4 registries carry Kubernetes-related agents (23 total entries)...\n```\n\n## Best Practices\n\n- Use the MCP server for automated workflows and agent-to-agent discovery\n- Use the web directory for manual exploration and comparison\n- Validate your agents.txt before publishing to ensure maximum discoverability\n- Check multiple registries — coverage varies significantly by domain\n\n## Common Pitfalls\n\n- **Problem:** Search returns too many results\n  **Solution:** Add protocol or registry filters to narrow the scope\n\n- **Problem:** MCP server not connecting\n  **Solution:** Ensure `npx` is available and run `npx -y @global-chat/mcp-server` manually first to verify\n\n## Related Skills\n\n- `@mcp-client` - For general MCP client setup and configuration\n- `@agent-orchestration-multi-agent-optimize` - For orchestrating multiple discovered agents\n- `@agent-memory-mcp` - For persisting discovered agent information across sessions\n\n## Limitations\n- Use this skill only when the task clearly matches the scope described above.\n- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.\n- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.","tags":["global","chat","agent","discovery","antigravity","awesome","skills","sickn33","agent-skills","agentic-skills","ai-agent-skills","ai-agents"],"capabilities":["skill","source-sickn33","skill-global-chat-agent-discovery","topic-agent-skills","topic-agentic-skills","topic-ai-agent-skills","topic-ai-agents","topic-ai-coding","topic-ai-workflows","topic-antigravity","topic-antigravity-skills","topic-claude-code","topic-claude-code-skills","topic-codex-cli","topic-codex-skills"],"categories":["antigravity-awesome-skills"],"synonyms":[],"warnings":[],"endpointUrl":"https://skills.sh/sickn33/antigravity-awesome-skills/global-chat-agent-discovery","protocol":"skill","transport":"skills-sh","auth":{"type":"none","details":{"cli":"npx
