Best Claude Code MCP servers

Runs proof-driven bug hunt rounds with /bughunt: each round proves one bug with a failing command the mod runs itself, fixes it, and proves the fix, and the loop stops on a blocked or unverified round. /bughunt collab runs a read-only scanner, planner and critic in sequence.

For mod development: runs a live check of plugins in a fresh Claude Code session in tmux, types the steps one by one, collects the pane and the transcript, then deletes the temp directory, its transcripts and the inline store files.

Before a vague prompt is sent, suggests a sharper rewrite; you choose: send improved, send yours, or edit the suggestion. Never rewrites silently.

Asks a council of models about a hard problem, when the model calls its tool or you run /council <question>: Claude models, and Gemini models when gemini-core has a key, answer in parallel, and the model of the session writes one verdict from their answers.

Put this Claude Code session on a full-duplex voice call. You talk while it codes, interrupt it at any time, and hear results read back. A spoken "yes" never approves anything: permission prompts stay on your keyboard. macOS only.

A Claude Code mod that draws Elizabeth (from Gintama) walking along a context-window progress bar above the prompt, with usage breakdown, turns left to auto-compact, rate limits and session cost.

A Claude Code plugin that gives the model a self-invoked Gemini advisor tool: it sends the full conversation plus the model's message to Gemini and returns a second opinion. Off by default until /gemini-advisor on; gemini-core holds the key, tier, model and thinking level.

A Claude Code plugin from the claude-mods marketplace that lists every file created or edited this session with git +/- line counts, plus one-click 'why?', summarize-all and self-review actions.

Draw diagrams, LaTeX math, and tool-result images inline in kitty-graphics terminals

A Claude Code plugin that ships a git commit skill and gates every Bash git command against it — blocking commits made without the skill, blanket `git add`, AI signature trailers, secrets, ignored paths, and unrequested pushes or branch changes.

OffiCraft is an AI studio running on your own Mac: hire several always-on AI members, hand them entire tasks, and watch their progress in a web console; when they need your approval, reply once. It runs the Claude Code or Codex on your machine.

A Claude Code plugin that notices when the agent is going in circles (the same command failing repeatedly or the same code rewritten over and over), tells the user, and prompts Claude to stop and rethink.
