Claude Code Explorer MCP
Let your coding agent browse, search, and inspect the Claude Code CLI source—tools, commands, and implementation—without cloning and grepping locally.
Overview
io.github.divu2025/codemaster is a MCP server for the Build phase that lets agents explore the Claude Code CLI source, tools, commands, and code search.

What problem does it solve?
Builders hacking on agent UX struggle to map Claude Code’s tools and commands without tedious local clones and manual search.
Who is it for?
Indie developers extending Claude Code, writing custom slash commands, or learning CLI architecture through conversational exploration.
Skip if: Users who only need documentation URLs with no MCP, or teams not using Claude Code who want generic GitHub search instead.
What do I get? / Deliverables
After adding the codemaster MCP server, your agent can browse and search Claude Code CLI internals on demand through stdio tools.
- MCP tools to browse Claude Code CLI structure, tools, and commands
- Search-oriented access to the published Claude Code source tree context
- Local stdio MCP integration without required API tokens in server.json

Journey fit
Exploring how Claude Code itself is built supports extending and debugging your agent stack during product construction, which maps to build rather than ship or launch. agent-tooling covers MCP servers that help you understand and customize the agent/CLI layer you depend on as a solo builder.
How it compares
Upstream Claude Code source explorer MCP—not a general repo indexer and not a skill marketplace.
Common Questions / FAQ
Who is codemaster for?
It is for developers using Claude Code who want MCP-driven navigation of the CLI’s tools, commands, and source without maintaining a separate exploration workflow.
When should I use codemaster?
Use it in the build phase while designing agent-tooling—when you need accurate references to how Claude Code implements tools before you fork or extend behavior.
How do I add codemaster to my agent?
Install @divyesh2000/codemaster from npm (v1.1.0), configure it as a stdio MCP server with the Node runtime hint, and connect it in Claude Code or Cursor MCP settings.
