Claude Code Tools & Extensions

Useful tools, plugins, and extensions for Claude Code.

MCP Servers

MCP (Model Context Protocol) servers are external processes that provide tools to Claude Code via a standardized protocol. They run alongside your session and extend Claude's capabilities.

Context7

Up-to-date documentation and code examples for any library, available directly in your Claude Code session.

• Website: https://context7.com/

• Setup:

  claude mcp add --scope user --transport http context7 https://mcp.context7.com/mcp --header "CONTEXT7_API_KEY: <YOUR_API_KEY>"
  

• Note: API key can be created for free after signing in at context7.com

Skills (Slash Commands)

Skills are a different extension mechanism from MCPs. They are prompt-based extensions invoked via /skill-name commands directly within Claude Code — no external server required.

Installing .skill packages

Skills are distributed as .skill files (ZIP archives containing a SKILL.md and optional scripts).

Option 1 — CLI (if claude command is available):

claude skill install --scope user my-skill.skill

Option 2 — Manual extraction (works everywhere, including VS Code extension):

# Python one-liner
python -c "import zipfile; zipfile.ZipFile('my-skill.skill').extractall('$HOME/.claude/skills')"

Skills are extracted into ~/.claude/skills/<skill-name>/. They become available in the next Claude Code session.

AST Index

Fast code search skill for Claude Code — find classes, symbols, usages, implementations, and more across large codebases using AST parsing.

• Repository: https://github.com/defendend/Claude-ast-index-search
• Usage: Invoke with /ast-index or related commands like "find class", "search for symbol", etc.

Packaged Skills

Packaged .skill files available in the skills/ directory:

• dolgolyov-claude-facts — Sync local project configuration with the central claude-code-facts knowledge base.
• dolgolyov-git-release-publisher — Generate release notes and push release tags for repos hosted on Gitea or GitHub.
• feature-planner — Plan and develop complex features using a structured, phase-based workflow with git integration, Markdown plans, review gates, and controlled merging.
