How to Set Up and Use Agentic MCP Skill
Agentic-MCP-Skill is a progressive MCP client that implements three-layer lazy loading to dramatically reduce token usage when working with MCP servers. Instead of loading all tool definitions upfront (which can consume thousands of tokens per conversation), it loads only server metadata in layer one, tool names and brief descriptions in layer two, and the full input schema for a specific tool only when it is about to be called. The project validates the AgentSkills.io pattern of progressive disclosure for MCP, and is aimed at developers building token-efficient agentic workflows who manage multiple MCP servers.
Prerequisites
- Node.js 18.0.0 or higher installed
- npm installed
- At least one MCP server you want to manage through the progressive client
- Claude Desktop, Cline, or another MCP-compatible host
Install Agentic-MCP globally
Install the package globally from npm so the agentic-mcp CLI is available on your PATH.
npm install -g @cablate/agentic-mcp
agentic-mcp --versionCreate the servers configuration file
Create an mcp-servers.json file that lists the downstream MCP servers you want to manage. Each entry includes the stdio command used to launch that server.
{
"servers": {
"playwright": {
"description": "Browser automation for web navigation, screenshots, clicks, and form filling",
"type": "stdio",
"command": "npx",
"args": ["@playwright/mcp@latest", "--isolated"]
}
}
}Start the Agentic-MCP daemon
The daemon manages connections to downstream servers and serves the three-layer lazy loading interface. Start it with your config path.
agentic-mcp daemon start --config /path/to/mcp-servers.jsonVerify the daemon and explore layers
Check daemon health, then walk through the three layers: metadata (layer 1), tool list (layer 2), and tool schema (layer 3).
# Layer 1 — basic server info
agentic-mcp metadata playwright
# Layer 2 — list available tools
agentic-mcp list playwright
# Layer 3 — full schema for a specific tool
agentic-mcp schema playwright browser_navigateConfigure your MCP client to use the daemon
Add the agentic-mcp server to your client config. The client communicates with the daemon which handles lazy loading transparently.
Agentic MCP Skill Examples
Client configuration
Add agentic-mcp to your claude_desktop_config.json pointing at your servers config file.
{
"mcpServers": {
"agentic-mcp": {
"command": "agentic-mcp",
"args": ["daemon", "start", "--config", "/path/to/mcp-servers.json"]
}
}
}Prompts to try
Use these prompts to exercise progressive tool loading through the Agentic-MCP layer system.
- "What MCP servers are currently available?" (triggers layer 1 metadata)
- "What tools does the playwright server provide?" (triggers layer 2 tool list)
- "Navigate to https://example.com and take a screenshot" (triggers layer 3 full schema + tool call)
- "List all available servers and their status"Troubleshooting Agentic MCP Skill
Daemon fails to start with 'config file not found'
Ensure the --config path is absolute and that the mcp-servers.json file exists and is valid JSON. Run 'cat /path/to/mcp-servers.json' to verify its contents.
Downstream servers are not reachable through the daemon
Confirm each downstream server's command can be run independently (e.g., 'npx @playwright/mcp@latest --isolated'). The daemon inherits your PATH, so make sure all commands are accessible.
agentic-mcp command not found after npm install -g
Run 'npm bin -g' to find where global binaries are installed and add that directory to your PATH, or use 'npx @cablate/agentic-mcp' as an alternative.
