What is mcp-standards-server CLAUDE.md?

Repository instructions for an MCP server that gives AI assistants access to software-development standards. MCP is a way for an AI assistant to call tools provided by another program.

Use them when developing the MCP server, adding or organizing standards, improving standard search, optimizing information for AI assistants, or mapping standards to NIST controls.

They describe how standards are selected, organized, searched, and checked, so contributors can work within the project's intended compliance and context-management system.

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	$0.02985	$0.02985
Opus 5.5	$0.01194	$0.01194
Sonnet 5.5	$0.00597	$0.00597
Haiku 4.5	$0.00298	$0.00298

Security

Grade A, and why

mcp-standards-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 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.

MCP Standards Server - LLM Context Management System

Last Updated: 2025-07-16
Status: ✅ FULLY OPERATIONAL SYSTEM - Complete standards ecosystem with verified Web UI and passing workflows

Project Overview

This project transforms the williamzujkowski/standards repository into a comprehensive LLM context management system by implementing a Model Context Protocol (MCP) server. The server provides intelligent, context-aware access to development standards, enabling LLMs to automatically select and apply appropriate standards based on project requirements.

Key Objectives

MCP Server Implementation: Build a robust MCP server that exposes the standards repository as accessible tools for LLMs
Intelligent Standard Selection: Implement rule-based and semantic search capabilities for automatic standard selection
Token Optimization: Create efficient, LLM-friendly formats for standards consumption
Compliance Integration: Support NIST 800-53r5 control mapping and compliance validation
Hierarchical Organization: Structure standards with clear metadata and relationships

Comprehensive Standards Coverage

The system now includes 25 comprehensive standards covering the entire software development lifecycle:

🚀 Specialty Domain Standards (8)

AI/ML Operations (MLOps) - Model lifecycle, ethical AI, monitoring
Blockchain/Web3 Development - Smart contracts, DeFi, security
IoT/Edge Computing - Device management, protocols, optimization
Gaming Development - Engine architecture, performance, multiplayer
AR/VR Development - Immersive experiences, spatial computing
Advanced API Design - REST, GraphQL, gRPC patterns
Database Design & Optimization - Schema design, performance tuning
Sustainability & Green Computing - Carbon footprint, efficiency

🔧 Testing & Quality Standards (3)

Advanced Testing Methodologies - Performance, security, chaos engineering
Code Review Best Practices - Review workflows, automated checks
Performance Tuning & Optimization - Profiling, caching, scaling

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.
