Connect your agent
Point your agent at Outer's MCP endpoint — one line per client, OAuth or emailed code.
Your agent talks to Outer over MCP at https://outer.now/mcp (Streamable HTTP,
OAuth 2.1). The first account tool call starts sign-in. After that the agent
retries and keeps going.
Client setup
| Client | Setup |
|---|---|
| Claude Code | claude mcp add --transport http outer https://outer.now/mcp, then run /mcp in Claude Code, pick outer and sign in in the browser that opens |
| claude.ai, Desktop, mobile | Settings → Connectors → Add custom connector → https://outer.now/mcp |
| Codex CLI, IDE, ChatGPT desktop app | codex mcp add outer --url https://outer.now/mcp, then codex mcp login outer |
| Perplexity | Settings → Connectors → add a custom MCP connector with https://outer.now/mcp (tested: OAuth sign-in, then @Outer build me …) |
| ChatGPT (chatgpt.com) | Add a custom connector with https://outer.now/mcp and sign in (tested) |
| Gemini | Add a custom MCP server with https://outer.now/mcp and sign in (tested) |
| Anything else | OAuth if supported, else the emailed-code fallback (see Sign in) |
How sign-in works
Claude, Codex, ChatGPT and Perplexity use OAuth. Your client opens Outer’s sign-in page:
- Enter your email and the emailed code.
- Accept the terms on first sign-in.
- Approve the client.
Clients without OAuth use two MCP tools instead. Details in Sign in.
When a limit or refusal hits, the tool result carries a user_message
written for you. Your agent relays it word for word.
What your agent builds
One of two starters (Pick a template): the interactive
app (Ilha and Void: lists, dashboards, anything with accounts), or the
website (Astro content site: landing pages, portfolios, blogs). Name
which one in your first prompt; the default is app.
Building it? The agent reads Agents → Quickstart.
