CleanSlice MCP Server

MCP (Model Context Protocol) server that gives AI coding agents access to the CleanSlice architecture documentation. Connect it to Claude, Cursor, Windsurf, or any MCP-compatible client so the AI knows how to build apps using CleanSlice conventions.

Installation

Run this command. See Claude Code MCP docs for more info.

claude mcp add --scope user --transport http cleanslice https://mcp.cleanslice.org/mcp

Remove --scope user to install for the current project only.

Tip: enforce MCP usage with CLAUDE.md

To make sure Claude Code always consults the CleanSlice MCP before writing any code, add the following to your project’s CLAUDE.md:

## CleanSlice MCP — Required

Before writing or modifying any code you MUST consult the CleanSlice MCP:

1. Call `get-started` to load the core architecture rules.
2. Call `list-categories` to see available documentation areas.
3. Call `search` with at least 2 task-relevant queries covering:
   (a) core implementation details for the feature you are building,
   (b) edge cases, constraints, or standards that apply.
4. Call `read-doc` to read the full document when search snippets aren't enough.

Do NOT guess conventions — always verify against MCP results first.

This ensures the agent reads CleanSlice docs at the start of every task, not after the fact.

Optional: add a Stop hook as a safety net

To catch cases where the agent skips the MCP despite the CLAUDE.md instruction, add this to .claude/settings.json:

{
  "hooks": {
    "Stop": [
      {
        "hooks": [
          {
            "type": "agent",
            "timeout": 180,
