CLAUDE.md

strapi-mcp-server CLAUDE.md is an instructions file for Claude Code from misterboe/strapi-mcp-server. It costs 1,044 tokens per session, scanned A, original, MIT.

A project instruction file for developing and debugging a server built with TypeScript and the Model Context Protocol (MCP), a standard for connecting AI tools to services.

In plain words
What is it for?
Use it to build or watch the project, start its development server, adjust log detail, enable monitoring or request tracking, sanitize logged data, and inspect the server with MCP Inspector.
Why use it?
It gives coding agents the commands, logging options, feature switches, and testing instructions needed to work consistently in the repository.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is misterboe/strapi-mcp-server's own configuration. It tells Claude Code how to work on strapi-mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything strapi-mcp-server configures →

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.

Security

Grade A, and why

strapi-mcp-server 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 8d 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

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Development Commands

  • npm run build - Compile TypeScript to build/ directory and make executable
  • npm run build:watch - Build with watch mode for development
  • npm run start - Start the compiled server from build/index.js
  • npm run dev - Run directly with ts-node for development
  • npm run dev:watch - Run with nodemon for hot reload during development

Debugging

Enable detailed logging via environment variables:

# Log levels: ERROR, WARN, INFO, DEBUG, TRACE
MCP_LOG_LEVEL=DEBUG npm run dev

# Enable/disable specific features
MCP_ENABLE_REQUEST_TRACKING=true
MCP_ENABLE_PERFORMANCE_MONITORING=true
MCP_SANITIZE_DATA=true
MCP_MAX_LOG_LENGTH=10000
MCP_INCLUDE_STACK_TRACE=true

# Enable MCP SDK debug logging
DEBUG=mcp:* npm run dev

Testing with MCP Inspector:

npm install -g @modelcontextprotocol/inspector
mcp-inspector  # Start inspector at http://localhost:5173

Architecture

Single-File Design

The entire server is implemented in src/index.ts (~1800 lines). Key sections in order:

  1. Logging System (lines ~56-424) - McpLogger class with structured JSON logging to stderr
  2. Zod Validation Schemas (lines ~454-627) - Input validation for all 5 tools
  3. Version Differences (lines ~747-826) - STRAPI_VERSION_DIFFERENCES constant for v4/v5
  4. Configuration (lines ~828-851) - Loads from ~/.mcp/strapi-mcp-server.config.json
  5. Server Setup (lines ~853-1024) - MCP server with capabilities including security policy
  6. Helper Functions (lines ~1026-1167) - getServerConfig, makeStrapiRequest, image processing
  7. Tool Handlers (lines ~1241-1675) - ListToolsRequestSchema and CallToolRequestSchema handlers
  8. REST/Upload Functions (lines ~1678-1812) - makeRestRequest, handleStrapiError

Validation Flow

All tool inputs are validated through Zod schemas before execution:

What this file has done since we first saw it

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.
