What is PrimeNG_MCP CLAUDE.md?

A project guide for an AI coding agent working on a TypeScript server that provides PrimeNG component documentation and Angular code examples.

Use it when building, running, testing, linting, formatting, or understanding the architecture of the PrimeNG documentation server.

It gives the agent the project’s commands, structure, testing process, and code-quality rules so it can work consistently in this repository.

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	$0.03180	$0.03180
Opus 5.5	$0.01272	$0.01272
Sonnet 5.5	$0.00636	$0.00636

Security

Grade A, and why

PrimeNG_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 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.

Project Overview

This is an MCP (Model Context Protocol) server that provides access to PrimeNG component documentation and generates Angular code examples. The server exposes tools that can be called by Claude Desktop or other MCP clients to retrieve component information, search components, and generate code snippets.

Version: 2.0.0 (Refactored Architecture)

Development Commands

Build and Run

npm run build        # Compile TypeScript to JavaScript in dist/
npm run watch        # Compile with watch mode (auto-recompile on changes)
npm run dev          # Run directly with tsx (no compilation needed)
npm start            # Run compiled version from dist/

Testing

npm test             # Run all tests with Vitest
npm run test:unit    # Run only unit tests
npm run test:coverage # Run tests with coverage report

Code Quality

npm run lint         # Lint TypeScript files
npm run lint:fix     # Auto-fix lint issues
npm run format       # Format code with Prettier
npm run format:check # Check code formatting

Architecture (v2.0)

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.
