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 | $0.00665 | $0.00665 |
| Opus 5.5 | $0.00266 | $0.00266 |
| Sonnet 5.5 | $0.00133 | $0.00133 |
| Haiku 4.5 | $0.00067 | $0.00067 |
Grade A, and why
laravel-loop 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.

Laravel Loop Package
Laravel Loop is a Model Context Protocol (MCP) server package for Laravel applications that enables AI assistants to interact with Laravel apps through multiple transport protocols (STDIO, Streamable HTTP, SSE). Uses Prism PHP for tool building.
Build/Test Commands
- Run tests:
composer test - Code formatting:
composer lint(Laravel Pint) - Static analysis:
composer analyse(Larastan) - All quality checks:
composer check(lint + analyse + test) - Run artisan commands:
vendor/bin/testbench - MCP server (STDIO):
php artisan loop:mcp:start [--user-id=1] [--debug] - Generate MCP config:
php artisan loop:mcp:config - Development server:
composer serve(testbench workbench)
Architecture
Core Components:
Loop- Main service class for managing tools/toolkitsMcpHandler- Handles MCP JSON-RPC protocol messagesToolinterface - Contract for individual tools (implements Prism\Tool)Toolkitinterface - Contract for tool collectionsCustomTool- Flexible tool builder for custom functionality
Transport Layer:
- STDIO transport via Artisan command using ReactPHP event loop
- Streamable HTTP transport (
/mcpendpoint) - SSE transport (
/mcp/sseendpoint, deprecated)
Design Patterns:
- All classes use
Makeabletrait for static factory methods - Contract-based architecture with clear interfaces
ToolCollectionfor managing groups of tools- Facade pattern (
Loop::tool(),Loop::toolkit())
Development Guidelines
Tool Development:
- Tools implement
Toolcontract withbuild()andgetName()methods - Use Prism's fluent API for parameter definition and tool configuration
- Group related tools in Toolkits that return
ToolCollection - Register tools in service providers using
Loop::tool()orLoop::toolkit()
Code Style:
- Uses Pest testing framework with Orchestra Testbench
- Strict typing with
declare(strict_types=1) - PSR-12 compliant via Laravel Pint
- Type hints required for parameters and return types
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.
