Apex Protocol – An open MCP-based standard for AI agent trading (apexstandard.org) AI

Apex Protocol (APEX) proposes an open, MCP-based standard that lets AI trading agents connect directly to brokers/execution venues using a shared set of tools, real-time state, and deterministic safety controls. It specifies canonical instrument IDs (to avoid per-broker symbol mapping), event-driven notifications over HTTP/SSE, session replay for reconnection, and a conformance-tested protocol surface for multiple languages. The standard is CC-BY 4.0 with reference implementations and governance via a technical advisory committee and an open RFC process.
