Epsilon3 MCP Server

Hosted, remote Model Context Protocol server exposing Epsilon3 procedures, runs, parts and inventory, and issues to MCP-capable assistants. Read-only in the current preview: it can search, open, query and trace records but cannot create, edit or delete. Authorization is OAuth 2.1 authorization-code with PKCE S256 and dynamic client registration, with fifteen scopes advertised via RFC 8414 and RFC 9728 metadata; an Epsilon3 API key may also be presented as a bearer token. Regional endpoints are published for the UK and EU.
