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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00248 | $0.00248 |
| Opus 5 | $0.00124 | $0.00124 |
| Sonnet 5 | $0.00050 | $0.00050 |
| Haiku 4.5 | $0.00025 | $0.00025 |
Grade A, and why
matter-controller-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 6d 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.

What it actually says
MCP "Matter Controller" Server - Development Guidelines
Build, Test & Run Commands
- Build:
npm run build- Compiles TypeScript to JavaScript - Watch mode:
npm run watch- Watches for changes and rebuilds automatically - Run server:
npm run start- Starts the MCP server using stdio transport - Run SSE server:
npm run start:sse- Starts the MCP server with SSE transport - Prepare release:
npm run prepare- Builds the project for publishing
Code Style Guidelines
- Use ES modules with
.jsextension in import paths - Strictly type all functions and variables with TypeScript
- Follow zod schema patterns for tool input validation
- Prefer async/await over callbacks and Promise chains
- Place all imports at top of file, grouped by external then internal
- Use descriptive variable names that clearly indicate purpose
- Implement proper cleanup for timers and resources in server shutdown
- Follow camelCase for variables/functions, PascalCase for types/classes, UPPER_CASE for constants
- Handle errors with try/catch blocks and provide clear error messages
- Use consistent indentation (2 spaces) and trailing commas in multi-line objects
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.
