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 | $0.02011 | $0.02011 |
| Opus 5 | $0.01006 | $0.01006 |
| Sonnet 5 | $0.00402 | $0.00402 |
| Haiku 4.5 | $0.00201 | $0.00201 |
Grade A, and why
mcp-client-laravel 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Overview
MCP Client for Laravel (redberry/mcp-client-laravel) is a Laravel-native client for Model Context Protocol (MCP) servers. It speaks JSON-RPC 2.0 over two transports — Streamable HTTP (spec 2025-03-26) and STDIO — and exposes them through a single facade so a Laravel app can list/call tools, read resources, and observe streamed events from any MCP-compliant server defined in config.
Commands
composer test # Run Pest tests
composer test-coverage # Tests with coverage
composer analyse # PHPStan (level 5, src + config)
composer format # Laravel Pint
bin/check # Pint → PHPStan → Pest in sequence (the local CI gate)
vendor/bin/pest --filter="test name" # Run a single test
vendor/bin/pest tests/Transporter/ # Run a directory
composer prepare # testbench package:discover (after dep changes)
CI runs Pint (fix-php-code-style-issues.yml), PHPStan (phpstan.yml), and Pest (run-tests.yml) on every push.

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.
