Build with Agent Skills

Use agent skills to guide AI coding assistants through MCP server design and implementation — reducing omitted security steps and inconsistent project layout.

Adapted from Build with Agent Skills.

Executive summary

When using Cursor, Claude Code or similar agents to scaffold MCP servers, load the official MCP agent skills so the assistant follows protocol conventions, SDK patterns and security baselines instead of inventing a one-off RPC shape.

Why skills help

Without skills	With MCP agent skills
Ad-hoc JSON over HTTP	Correct transports (stdio / Streamable HTTP)
Untyped tool args	JSON Schema / SDK validators
Secrets in prompts	Env-based configuration
Missing consent UX notes	Documented human-in-the-loop expectations

Recommended workflow

1. Open the official guide: Build with Agent Skills.
2. Install or enable the MCP-related skills in your coding agent.
3. Prompt with constraints: language SDK, local vs remote, tool inventory, data sensitivity.
4. Generate the server scaffold.
5. Validate with MCP Inspector before connecting a host.
6. Diff against security best practices.

Enterprise guardrails to include in the prompt

• Allowed directories / APIs the server may touch
• Whether tools may write or only read
• Auth requirements for remote exposure
• Logging and PII redaction expectations
• Target MCP protocol version

Negative cases

• Agent invents a custom WebSocket protocol “compatible with MCP” → reject; use official SDK.
• Skills outdated vs current SDK → pin skill version and re-check official docs.
• Generated server logs to stdout on stdio → fix before shipping.

Key takeaways

• Agent skills encode protocol taste into coding assistants.
• Always verify generated servers with Inspector and security review.
• Treat skills as accelerators, not a substitute for the specification.
