Era Devin plugin

Era is Eon's synthetic-company platform at https://console.era.eon.io. This plugin gives Devin Era's console MCP server and the era skill.

Before anything else: Connect the server

Installing the plugin is not enough. The era server is OAuth-protected and the sign-in is per person, so the first thing to do after installing is:

1. In the Devin app open Customize → MCPs.
2. Under From plugins, find the era row and click Connect.
3. Sign in to the Era console (Google or email) and approve.
4. Start a new session — sessions only pick the connection up at start.

Until you do this, every call Devin makes to the server answers 401 Unauthorized (Devin's error text points at "Settings > MCP Marketplace"; the place is Customize → MCPs) and the skill makes Devin stop and ask you for exactly these steps.

No Era account yet? Request one at https://console.era.eon.io/access.html. When an operator approves it, Era emails you a first sign-in; then do the steps above.

Install

Customize → Plugins → Add plugin → From repository, eon-io/era-devin-plugin (or devin plugins install eon-io/era-devin-plugin with the Devin CLI). The plugin reaches your next session; then Connect as above.

Installing for a whole organization: keep Personal access on the server so each member signs in as themselves - one shared login would put everyone's companies on one account. Each member still does the Connect step once.

What the skill covers

Provisioning a synthetic company over the console MCP (create_design_partner), reaching its systems over REST with the tenant token or as custom MCP servers, what to do on a 401, and how to investigate across the connected systems.
