mcp-server CLAUDE.md

mcp-server CLAUDE.md is an instructions file for coding agents from passgage/mcp-server. It costs 1,389 tokens per session, scanned A, original, MIT.

Repository instructions for working on Passgage API MCP, a TypeScript and Node.js server that lets AI assistants use Passgage's workforce-management API. They describe the project structure, development commands, and code-quality checks.

In plain words
What is it for?
They are for developing and validating the Passgage MCP server, including its API client, authentication, types, tests, and production build.
Why use it?
They give an agent the project's expected workflow and the commands used to build, test, lint, and type-check changes. This reduces guesswork when modifying the repository.

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

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 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.

Project Overview

This is a comprehensive Passgage API MCP (Model Context Protocol) Server built with TypeScript and Node.js. The server provides 130+ tools to interact with the complete Passgage Public API surface area, enabling AI assistants like Claude to manage workforce operations, approvals, time tracking, and more.

Development Commands

Build and Run

  • npm run build - Compile TypeScript to JavaScript
  • npm run dev - Development mode with hot reload using tsx
  • npm start - Start production server from dist/
  • npm run type-check - TypeScript type checking without compilation

Code Quality

  • npm run lint - Run ESLint on TypeScript files in src/ directory
  • npm run lint:fix - Auto-fix linting issues
  • npm test - Run Jest tests with NODE_OPTIONS='--experimental-vm-modules'
  • npm run type-check - TypeScript type checking (recommended before commits)

Project Architecture

Core Components

  • src/api/client.ts - Passgage API client with JWT auth, auto-refresh, error handling
  • src/types/api.ts - Complete TypeScript definitions for Passgage API
  • src/config/index.ts - Environment configuration and validation
  • src/index.ts - MCP server implementation with stdio transport

Tool Categories

  • src/tools/auth.ts - Authentication tools (login, logout, refresh, status)
  • src/tools/crud.ts - CRUD operations for 25+ Passgage services (125 tools)
  • src/tools/specialized.ts - Advanced tools (file upload, approvals, search, export)

MCP Tools Structure

The server provides 133 total tools:

  • 8 Authentication tools - JWT session and mode management
  • 125 CRUD tools - 5 operations × 25 services (list, get, create, update, delete)
  • 8 Specialized tools - File upload, bulk approvals, search, dashboard stats

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.
