Lesson 15MCP

Advanced MCP

Resources, prompts, tool search

MCP Resources

Resources are data that servers expose to Claude. You can mention them via @.

> Using @postgres://users/schema, show the users table structure

MCP Prompts

Prompts are predefined command templates from MCP servers.

/mcp-github:create-pr — create Pull Request with description

Tool Search

When there are many MCP servers, Claude searches for the right tool by description.

> Find a tool for creating issues

@ Resource Mentions

Use @ to reference MCP resources in your queries:

@postgres://schemaDatabase schema

@github://issues/123Specific issue

@file:///path/to/doc.mdLocal file

@notion://page/abcNotion page

> Using @postgres://users/schema, write a migration to add email_verified field

Claude Code as MCP Server

Claude Code itself can act as an MCP server for other applications:

// claude-code-mcp-server
// Claude Code сам может быть MCP сервером

// В другом приложении:
{
  "mcpServers": {
    "claude-code": {
      "command": "claude",
      "args": ["mcp-serve"]
    }
  }
}

// Теперь другие агенты могут использовать Claude Code

💡 This allows using Claude Code capabilities from IDE plugins, CI/CD, or other AI agents

Output Management

MCP servers can return lots of data. Claude manages this:

Token Limits

Servers can specify maximum tokens in response

maxTokens: 5000

Pagination

Large results are split into pages

cursor: "next_page_token"

Advanced Tips

•Use @ mentions for precise context specification
•MCP Prompts work like custom commands
•With many servers, Claude automatically searches for the right tool
•Claude Code as MCP server — powerful automation pattern
