MCP PHP Schema Reference

Quick Navigation

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.

JSON Data Files

For programmatic access:

data/schema-index.json - Lightweight discovery index
data/schema-common.json - Common domain types
data/schema-server.json - Server domain types
data/schema-client.json - Client domain types

Search Scripts

# Search types by name
./scripts/search-types.sh "Resource"

# Get type details
./scripts/get-type.sh "CallToolRequest"

# Find RPC method
./scripts/find-rpc.sh "tools/call"

Install mcp-php-schema and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.
