Claude Code, Codex and Cursor

Connect your coding assistant to Era over MCP with a browser sign-in — no key to copy — and let it read and act with your permissions.

Era's MCP server is https://app.getera.io/api/mcp (streamable HTTP). Add it to your assistant without a key: the first time it connects, your browser opens Era's consent card, you pick the workspace, which modules it may reach and whether it may only read, and the assistant gets an OAuth token bound to exactly that. It never reaches further than you can in Era, and you can disconnect it any time under Settings → Advanced → API keys → Connected apps.

Terminal

claude mcp add --transport http era https://app.getera.io/api/mcp

Then, inside Claude Code:

Claude Code

/mcp

Choose era → Authenticate. Your browser opens Era's consent card; approve it and come back — the status turns to connected.

Terminal

codex mcp add era --url https://app.getera.io/api/mcp
codex mcp login era

codex mcp login era opens Era's consent card in your browser. If you prefer the config file, the same server in ~/.codex/config.toml is:

~/.codex/config.toml

[mcp_servers.era]
url = "https://app.getera.io/api/mcp"

.cursor/mcp.json

{
  "mcpServers": {
    "era": { "url": "https://app.getera.io/api/mcp" }
  }
}

Cursor opens Era's sign-in the first time it connects to the server (Settings → MCP shows its state).

Print it for your setup

If you have the CLI, era mcp prints these snippets with your Era's address (era mcp --client claude|codex|cursor for one).

What the assistant gets

Only what the consent allows, as tools:

Tool	What it does
`read__…`	Reads the modules it may read — customers, orders, bookings, invoices… — with your row rules and masked fields.
`recall_memory`	Searches the business's memory (Brain). Needs the AI module.
`era__<module>__<action>`	Every action it may call, e.g. `era__crm__capture_lead`, `era__retail__fulfil_order`. Same input, preconditions and errors as the API; each runs as you and lands in the activity feed.

Try it

A first, read-only request

Using Era: list my 10 newest unfulfilled orders with customer, total and payment status.
Don't change anything.

A first write

Using Era: capture a lead for the customer [email protected] — she wants the yearly plan.
Show me the tool call before you make it.

Troubleshooting

What you see	Why, and what to do
The browser never opens	Run the client's sign-in again (`/mcp` → Authenticate, `codex mcp login era`). Make sure you are signed in to Era in that browser.
A tool you expected is missing	The token does not reach that module, or your role does not allow it. Disconnect the app and connect again with more modules, or ask an admin.
`409` with a code such as `order_not_fulfillable`	A precondition of the action — the reference lists every code and what it means.
`401` after a while	The connection was revoked or your seat removed. Connect again.

Prefer an API key instead of a sign-in (for a shared machine or CI)? See MCP server.
