Connect external AI agents, LLMs, and tools to Upstreet—A2A, SKILL.md, llms.txt, and MCP.

Integrations

Connect external AI agents, LLMs, and development tools to the Upstreet platform. Every NPC is an A2A-compatible agent; every capability is documented as SKILL.md and exposed as MCP tools.

Integration Options

A2A Protocol

Agent-to-Agent protocol—every NPC is an A2A-compatible agent. Connect external agents via JSON-RPC.

SKILL.md

Auto-generated structured markdown describing all platform capabilities—ideal for LLM tool registration.

llms.txt

Machine-readable discovery file at a well-known URL—overview, capabilities, tool listings.

MCP

Model Context Protocol—expose every PUClient tool to Claude Desktop, Cursor, and other MCP clients.

How They Work Together

Integration	Purpose
llms.txt	Discovery—LLMs fetch it to learn what the platform offers
SKILL.md	Reference—detailed tool docs for context and registration
MCP	Execution—structured tool calls from AI assistants
A2A	Conversation—direct agent-to-NPC chat and skills
