What is mcp-server-clerk CLAUDE.md?

Project instructions for a Clerk MCP server, which lets AI assistants call Clerk’s user and organization management API. They describe the project’s Nuxt 3 setup, structure, and main design ideas.

Working on the Clerk MCP server: understanding its tools, middleware, API connection, project structure, and TypeScript or Nuxt code.

They give an AI coding assistant the project context needed to understand and change the code consistently. This reduces time spent working out the technology stack and file layout.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.03286	$0.03286
Opus 5.5	$0.01314	$0.01314
Sonnet 5.5	$0.00657	$0.00657

Security

Grade A, and why

mcp-server-clerk CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md — Clerk MCP Server

Project Overview

This is a Model Context Protocol (MCP) server for Clerk, built with Nuxt 3 and the @nuxtjs/mcp-toolkit module. It exposes Clerk's Backend API (organizations, users, memberships, invitations, metadata) as MCP tools that AI assistants (Claude, Cursor, VS Code Copilot, Windsurf) can call.

The MCP endpoint is served at /mcp by the Nuxt dev server.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
