Best Claude Code MCP servers

The fabric-data-app subdirectory in the Power BI Agentic Dev marketplace fork, providing Power BI and Microsoft Fabric skills, agents and hooks for Claude Code, Copilot CLI and Codex.

A Claude Code mod that refuses prose Claude writes with an em dash, an en dash or a double hyphen used as punctuation, and tells Claude which lines to rewrite.

Records which real checks ran and which files changed after them; status line, /evidence, and an evidence tool Claude reads before claiming tested.

Build, format, and review Power BI reports (PBIR), with a report pane that follows pbir.

Keeps a long-running agent's working notes through every compaction: briefs the summarizer, re-attaches the notes after the summary, and shows them in a panel you can steer.

A Claude Code plugin (a mod) that renders A2UI blocks-dialect atoms natively in Claude Code panes, as terminal cells. Atoms that list `claude-code` in their `surfaces.works_on` draw here; any other atom shows a `[type: not drawn on this surface]` placeholder instead of failing.

A .NET / DDD oriented Claude Code toolkit sample: a spec → plan → TDD implementation → audit skill chain, path-scoped rules, agents and hooks, installed by cherry-picking folders into .claude/.

Context-card and pr-pane: adds a usage card above the Claude Code prompt and a sidebar showing the status of all sessions.

A pixel Clawd acts out every tool call above the prompt; helpers wander in by model color. Terminal-first, no model calls.

TDD batch skill from a .NET/DDD Claude Code toolkit with a spec → plan → TDD implementation → audit chain.

Claude Code plugin mod adding a context/usage status line above the prompt plus a sessions pane for monitoring other running sessions.

cc-footprint shows context usage, growth speed, source breakdown, MCP cost share, 5-hour and weekly quota reset times, and RAM usage for the session process tree on every Claude Code session's status line. It also provides a plugin that notifies you when context jumps during one turn or is about to compact automatically, with full details in a /footprint panel. Supports Windows and Linux.
