simplifier-mcp CLAUDE.md

simplifier-mcp CLAUDE.md is an instructions file for coding agents from simplifier-ag/simplifier-mcp. It costs 741 tokens per session, scanned A, original, MIT.

Development instructions for an MCP server that connects AI assistants to the Simplifier low-code platform through its REST API. Simplifier is a platform for creating integrations and server-side JavaScript business logic.

In plain words
What is it for?
Use it when configuring, building, testing, or extending the server for Simplifier connectors and BusinessObjects.
Why use it?
It documents the project structure and the required Simplifier token, which behaves like a short-lived session credential and may need daily renewal. It also records the current implementation status.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

simplifier-mcp 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 3d 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 Development Notes

This file contains development notes and instructions for Claude when working on this project.

Project Overview

This is a Model Context Protocol (MCP) server for the Simplifier Low Code Platform. The server enables AI assistants to interact with Simplifier's REST API to create and manage:

  • Simplifier Connectors: Integration components that connect external systems
  • BusinessObjects (BOs): Server-side executed JavaScript functions for business logic

Key Implementation Details

Authentication

  • Simplifier uses SimplifierToken (not API keys)
  • Token has session-like behavior and needs daily refresh (depending on token settings of Simplifier)
  • User must obtain token daily and configure it in environment variables

Configuration

  • Base URL of Simplifiers REST API configured via SIMPLIFIER_BASE_URL environment variable
  • Default development URL: http://localhost:8080 (matches user's Simplifier server port)
  • Configuration validation in src/config.ts

Current Status

  • Infrastructure: ✅ Complete (TypeScript, Jest, ESM, build system)
  • MCP Server: ✅ Basic server with empty capabilities
  • API Client: ✅ Structure in place with authentication placeholders
  • Tests: ✅ All tests passing
  • Capabilities: ❌ Empty arrays - tools, resources, prompts need implementation

Testing

  • Run tests: pnpm test
  • Build project: pnpm run build
  • Start server: pnpm run dev or pnpm start
  • Test MCP protocol: echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/list"}' | node dist/index.js

File Structure Notes

  • src/tools/index.ts - Empty tools array, ready for Simplifier tool implementations
  • src/resources/index.ts - Empty resources array, ready for platform data access
  • src/prompts/index.ts - Empty prompts array, ready for guided operations
  • src/client/ - API client with placeholder authentication
  • __tests__/ - Comprehensive test suite covering all modules

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.
