# 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:**
```bash
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](https://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).
**Manual extraction** (works everywhere, including VS Code extension):
```bash
# 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/](skills/) directory:
- **dolgolyov-dev-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.
