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.

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 | $0.01150 | $0.01150 |
| Opus 5 | $0.00575 | $0.00575 |
| Sonnet 5 | $0.00230 | $0.00230 |
| Haiku 4.5 | $0.00115 | $0.00115 |
Grade A, and why
php-mcp-sdk-main 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 4d 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.

PHP MCP SDK Architecture Guide
This is the PHP implementation of the Model Context Protocol (MCP) SDK, following the patterns established by the TypeScript SDK.
Core Architecture Principles
- Follow TypeScript SDK Patterns: The PHP SDK should mirror the TypeScript SDK's architecture while using PHP idioms
- Type Safety: Use PHP 8+ type declarations, union types, and attributes extensively
- Async Support: Utilize ReactPHP or similar for async operations where the TypeScript SDK uses Promises
- PSR Standards: Follow PSR-4 for autoloading, PSR-12 for coding standards, PSR-7 for HTTP messages

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.

php-mcp-sdk-main is a cursor rule published in the GitHub repository dalehurley/php-mcp-sdk (27 stars, last pushed 9mo ago), licensed MIT. It adds 1,150 tokens to every session, about $0.0057 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
