SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill resolves the complexity of integrating external capabilities into Anthropic Managed Agents by providing a clear framework for choosing between prebuilt, MCP-based, and custom host-side tools.

Core Features & Use Cases

  • Tool Categorization: Clearly distinguishes between prebuilt container tools, vault-backed MCP integrations, and custom host-side logic.
  • Security & Auth Management: Provides guidance on using Anthropic vaults for secure credential handling and OAuth token refreshing.
  • Use Case: Use this skill to determine whether to use a prebuilt bash tool for file operations or to build a custom tool on your own server for internal API calls requiring secret keys.

Quick Start

Configure the agent to use the GitHub MCP server by declaring the URL in the mcp_servers block and attaching the vault ID during session creation.

FAQPage Schema
How do I configure tools for Anthropic Managed Agents?

To configure tools for Anthropic Managed Agents, you select between prebuilt container tools, vault-backed MCP integrations, or custom host-side logic based on your credential requirements and execution location. You define MCP servers in the mcp_servers block and attach vault IDs during session creation.

What is the difference between prebuilt, MCP-based, and custom tools in Anthropic Managed Agents?

Prebuilt tools are ready-to-use container tools for standard operations, MCP-based tools connect to external servers via vault-backed authentication, and custom tools run host-side logic for complex internal API integrations requiring specific credential handling.

How do I secure credentials and manage OAuth tokens for Anthropic Managed Agent tools?

You secure credentials for Anthropic Managed Agent tools by using Anthropic vaults for secure credential handling and OAuth token refreshing. You attach the specific vault ID during session creation to enforce secure execution.

When should I use a custom host-side tool instead of a prebuilt tool for Anthropic Managed Agents?

You should use a custom host-side tool instead of a prebuilt tool when your use case involves internal API calls requiring secret keys or complex logic that cannot be executed in the prebuilt container environment.

How do I integrate the GitHub MCP server with an Anthropic Managed Agent?

To integrate the GitHub MCP server, declare the server URL in the mcp_servers configuration block and attach the corresponding vault ID for authentication during the session creation process.
