How do I handle secrets in MCP configurations?

Use environment variable interpolation with the ${VARIABLE_NAME} syntax within your transport settings to securely pass tokens and keys.

Which transport should I use for local Claude Code plugins?

The stdio transport is recommended for local development as it is secure, low-latency, and requires no network port configuration.

What are the target response times for MCP tools?

Developers should aim for <50ms for simple fetches and keep complex operations under 2 seconds to maintain a smooth, responsive AI interaction.

What is the standard naming convention for MCP tools?

Use the pattern mcp__ __ in snake_case to ensure discoverability and prevent collisions within the Claude Code ecosystem.

Desarrollo de API

Implements standardized patterns and best practices for building Model Context Protocol (MCP) servers within the Claude Code ecosystem.

The MCP Standards skill provides a comprehensive framework for developing robust, predictable, and maintainable MCP servers. It establishes critical conventions for directory structures, tool naming patterns, and transport configurations including stdio, HTTP, and WebSockets. By following these industry-standard implementation patterns, developers can ensure their Claude Code plugins feature high-performance tool integrations, consistent error handling, and seamless discoverability across the plugin marketplace, ultimately reducing the maintenance burden for complex multi-model workflows.
