Why should I follow these MCP standards?

Standardization ensures your tools are predictable for users, easier for the AI to identify, and significantly simpler to debug and maintain over time.

What are the target response times for MCP tools?

Simple fetch operations should target under 50ms, while complex analysis should ideally stay under 3 seconds to ensure a fluid user experience.

Which transport should I use for local MCP servers?

The stdio transport is the standard for local development and command-line usage as it provides low latency and requires no network configuration.

What is the standard naming convention for MCP tools?

Tools should follow the pattern mcp__ __ using snake_case to ensure consistency and discoverability across the ecosystem.
