Clean Slice 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. Its README documents 4 tools, including get-started, list-categories, search. It is available as a remote MCP endpoint.
Teams that want a hosted documentation endpoint instead of running a local process. The project is written in TypeScript.

01 · Install Clean Slice
Claude Code
claude mcp add cleanslice-mcp --transport http https://mcp.cleanslice.org/mcpClaude Desktop / Cursor / VS Code - add to config
{
"mcpServers": {
"cleanslice-mcp": {
"url": "https://mcp.cleanslice.org/mcp"
}
}
}Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
Using another client? Same JSON, different key

Security posture
What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.
runs as remote - your agent's requests go to mcp.cleanslice.org
endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect
license MIT - declared in the repository
registry namespace io.github.CleanSlice is GitHub-verified and matches the repo owner
03 · What Clean Slice can do
Prose above is summarized from the project's README and registry record - no invented capabilities.
What you can build
With this server connected, an agent can read the essential CleanSlice rules and conventions. Call this first, list all documentation categories available for search filtering, search docs by query, category, framework, phase, or tags. Returns snippets (keyword-in-context excerpts) and document paths, and read the full content of a specific document by path. Use after search to get complete docs.
