mcp-reference-server CLAUDE.md

mcp-reference-server CLAUDE.md is an instructions file for coding agents from commerce-operations-foundation/mcp-reference-server. It costs 1,138 tokens per session, scanned A, original, MIT.

Project instructions for an MCP server that connects AI agents with order-fulfilment systems using the Order Network eXchange Standard. MCP, or Model Context Protocol, is a way for AI tools to interact with external services through a defined interface.

In plain words
What is it for?
Use them when developing the server, creating fulfilment-system adapters, changing order-data schemas or working with backend capability definitions. They cover development, unit tests and integration tests.
Why use it?
They show where the server code, adapters, data schemas and integration guides belong. They also provide the commands needed to build, run and test the project.

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-reference-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 4d 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

Commerce Operations Foundation MCP Server - implements the Order Network eXchange Standard (onX) providing a standardized interface between AI agents and fulfillment systems via the Model Context Protocol (MCP).

Project Structure

/server          - Core MCP server implementation (main development here)
/adapter-template - Template for creating custom fulfillment adapters
/schemas         - JSON Schema definitions for domain models
/backends        - Backend-specific capability manifests
/docs            - Specification and integration guides

Development Commands

All primary development happens in /server. Run these from the server/ directory:

# Build
npm run build          # Compile TypeScript
npm run dev            # Run with hot reload (vite-node)
npm start              # Run production build

# Test
npm test               # Build + run all tests
npm run test:unit      # Unit tests only
npm run test:integration  # Integration tests
npx vitest tests/unit/adapters/adapter-factory.test.ts  # Single test file
npx vitest tests/unit --grep "pattern"                  # Tests matching pattern

# Quality
npm run lint           # ESLint
npm run format         # Prettier
npm run typecheck      # Type checking

For adapter development (adapter-template/):

npm run build          # tsc
npm run dev            # tsc --watch
npm test               # Jest with ES modules

Architecture

MCP Server (server/)

Three-layer architecture:

  1. Protocol Layer - MCP SDK integration, stdio transport, request routing
  2. Service Layer - ServiceOrchestrator facade, AdapterManager, health monitoring, validation
  3. Adapter Layer - AdapterFactory with dynamic loading (built-in, NPM, or local adapters)

Tools: 5 action tools + 7 query tools defined in src/tools/, registered via registerTools() in ToolRegistry

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.
