What is mcp-client-laravel CLAUDE.md?

Project instructions for a Laravel package that connects applications to Model Context Protocol servers. Laravel is a PHP framework, and MCP is a standard way for applications to expose tools and data to AI clients.

Understanding the package structure, connecting to MCP servers over HTTP or standard input/output, and running its local quality checks.

They give developers a map of the package, its request flow, supported connection methods, and the commands used to format, analyse, and test it.

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	$0.02011	$0.02011

Security

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 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

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.

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.
