What exists today

What SignalEDI exposes

The same modules that power the developer overview, rendered for buyers comparing EDI API options.

REST and SDKs for application traffic

SignalEDI parses, validates, and exchanges supported business documents over REST, with SDKs for typed application code. Webhooks carry signed delivery events for acknowledgements. Partner exchange requires a configured connection and environment before documents move.

MCP for agent workflows

SignalEDI publishes the @signaledi/mcp-server package (18 tools, registry io.github.SignalEDI/mcp-server) for synthetic evaluation with compatible agent tools. Local MCP guidance is not a billable API call. SignalEDI builds to your trading partner's requirement. Scope is confirmed during setup.
