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 | $0.02852 | $0.02852 |
| Opus 5 | $0.01426 | $0.01426 |
| Sonnet 5 | $0.00570 | $0.00570 |
| Haiku 4.5 | $0.00285 | $0.00285 |
Grade A, and why
mcp-adr-analysis-server copilot-instructions.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.

MCP ADR Analysis Server - AI Coding Agent Instructions
Project Overview
This is a Model Context Protocol (MCP) server that provides AI-powered architectural analysis and ADR (Architectural Decision Record) management. The server integrates with AI assistants (Claude, Cline, Cursor) via the MCP protocol and uses OpenRouter.ai for generating actual analysis results instead of prompts.
Core Architecture: MCP server (src/index.ts) exposes 73 tools through @modelcontextprotocol/sdk that call into utilities for AI execution, caching, session/tool-usage tracking, and memory management.
Critical Technical Conventions
ESM-Only Module System
- Pure ESM (no CommonJS): All imports must use
.jsextensions even for TypeScript files - Use
import.meta.url(never__dirname). Helper:getCurrentDirCompat()fromsrc/utils/directory-compat.ts - Example:
import { foo } from './bar.js'(note.jsextension) package.jsondeclares"type": "module"and targets ES2022
TypeScript Configuration
- Strict mode enabled: All strict type checks are enforced (see
tsconfig.json) - Output directory:
dist/src/with source maps and declarations - Tree-sitter native modules are mocked in Vitest (
tests/__mocks__/)
Testing Requirements
- Coverage threshold: 85% (branches, functions, lines, statements)
- Vitest with native ESM and TypeScript support
- Run tests with:
npm testormake test - Tree-sitter modules must be mocked for Vitest environment
Development Workflows
Build & Run
npm run build # Clean + TypeScript compile to dist/
npm start # Run production server from dist/
npm run dev # Development server with tsx hot-reload
make ci # Full pipeline: security, lint, test, build
Testing Strategy
npm test # All tests with Vitest
npm run test:coverage # Generate coverage report
npm run test:unit # Unit tests via scripts/test-infrastructure.sh
npm run test:integration # Integration tests
npm run test:mcp-interactive # Test with MCP Inspector
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.

mcp-adr-analysis-server copilot-instructions.md is an instructions file published in the GitHub repository tosin2013/mcp-adr-analysis-server (33 stars, last pushed 2d ago), licensed MIT. It adds 2,852 tokens to every session, about $0.0143 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
