README

The official MCP extensions for the Nexus MCP SDK, each with its server and client halves: tasks, MCP Apps, and the OAuth extension grants.

Important

This repository is a read-only subtree split of NexusPHP/mcp. Open issues and pull requests there. Anything opened here is closed automatically with the same pointer.

Installation

composer require nexusphp/mcp-extensions

This package depends on both nexusphp/mcp-server and nexusphp/mcp-client, since every extension ships both halves. The umbrella nexusphp/mcp includes it.

What is inside

Namespace	Extension
Nexus\Mcp\Extension\Tasks	Long-running tool calls brokered into polled tasks (SEP-2663)
Nexus\Mcp\Extension\Apps	ui:// views linked to tools (SEP-1865)
Nexus\Mcp\Extension\Auth	Client credentials (SEP-1046) and enterprise-managed authorization (SEP-990)

Each extension keeps its capability identifier and protocol literals on a vocabulary class (Tasks, Apps, Auth\ClientCredentials\ClientCredentials, Auth\Enterprise\EnterpriseAuthorization), with Server and Client subnamespaces for the two halves.
