Agent DEV-MCP (pointer)
Guide for creating quality MCP (Model Context Protocol) servers.
Context
<arguments>
Delegate to the vendor toolkit
claude-base's prior dev-mcp content is superseded by anthropics/skills › mcp-builder — the protocol authors' own skill. It covers MCP server design (workflows-not-endpoints, tool annotations, input validation, actionable errors, evaluation) for both Python (FastMCP) and the Node/TS SDK, at a depth and currency a hand-maintained checklist cannot match; this command wrapped a protocol the vendor owns.
Install:
# Vendor path (verify on their README):
npx skills add anthropics/skills
# Fallback — clone the canonical repo:
git clone --depth 1 https://github.com/anthropics/skills ~/dev/vendor-skills/anthropic
ln -s ~/dev/vendor-skills/anthropic/skills/mcp-builder ./.claude/skills/mcp-builder
Recipe entry: docs/recipes/recommended-vendor-skills.md §"Anthropic — mcp-builder". Reduction rationale: specs/graduation-supply-audit/spec.md.

YOU MUST validate all inputs (Pydantic/Zod) and return actionable errors; NEVER expose internal technical details in error messages.
