What it does
Global Chat Agent Discovery is an agent skill from sickn33/agentic-awesome-skills. Discover and search 18K+ MCP servers and AI agents across 6+ registries using Global Chat's cross-protocol directory and MCP server.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Tasks that involve MCP servers
Example prompts
- “/global-chat-agent-discovery”
Requirements
- Node.js
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Visit the search page and enter your query
- Filter by protocol (MCP, A2A, agents.txt)
- Filter by registry source
- View server details, capabilities, and installation instructions
What it can do on your machine
Read from SKILL.md and the folder at commit b84d35a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npmnpx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
global-chat.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Global Chat Agent Discovery loads about 1.1k tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 418 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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-serverAdd 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:
- Visit the search page and enter your query
- Filter by protocol (MCP, A2A, agents.txt)
- Filter by registry source
- View server details, capabilities, and installation instructions
Option 3: Validate Your agents.txt
If you maintain an agents.txt file, use the free validator:
- Go to https://global-chat.io/validate
- Enter your domain or paste your agents.txt content
- 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
npxis available and runnpx -y @global-chat/mcp-servermanually 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.
