Navigate and understand the MCP PHP schema. Use when implementing MCP clients/servers, understanding protocol types, or finding the right DTO for a task.

🔥🔥🔥✓ VerifiedFreeQuick setup

#git

🧰 Not standalone. This skill ships with wordpress/php-mcp-schema and only works together with that tool — install the tool first, then add this skill.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

MCP PHP Schema Reference

Server types (resources, tools, prompts): reference/server.md
Client types (sampling, elicitation, roots): reference/client.md
Common types (protocol, JSON-RPC): reference/common.md
RPC methods: reference/rpc-methods.md
Factories: reference/factories.md

Schema Structure

3 domains, 17 subdomains, 164 types total.

Domains Overview

Domain	Types	Purpose
Common	59	Protocol base, JSON-RPC, content blocks
Server	59	Tools, resources, prompts, logging
Client	46	Sampling, elicitation, roots, tasks

Common Patterns

Finding a Request/Result Pair

Check rpc-methods.md for method name
Look up request type in domain file
Find corresponding result type

Using Factory Classes

Factories create the correct DTO from discriminator values. See factories.md for patterns.
