Build strategies by asking.

Pick the app you already use. Approve once. Then ask — it builds, compiles, and backtests in your Spera account.

Connect Claude

Anthropic’s connector dialog cannot be pre-filled by any MCP server, so the button copies the URL and opens the dialog for you. One paste is the whole difference.

Copy URL & open Claude

One click: the URL goes to your clipboard and Claude opens on the Add custom connector dialog. Paste, confirm, sign in.

Why can’t this be fully automatic?

Anthropic’s Add custom connector dialog cannot be pre-filled by a link — no MCP server can do it. That changes once Spera is listed in Claude’s connector directory, which turns this into a Connect button. Until then, paste is the shortest path that exists.

A localhost URL never works here either — Claude Desktop and claude.ai dial from Anthropic’s servers, not your machine.

  1. Paste into the dialog that opens (Ctrl/Cmd+V), then confirm.

  2. Sign in to Spera and approve the permissions.

  3. Fully quit Claude — not just a new chat — then reopen it.

You’re done when Settings → Connectors shows Spera as connected.

Then ask this
What Spera projects do I have?

Spera tools appear, and the assistant lists your projects — or says you have none.

Need a free Spera account first? Create one. The connector has nothing to attach to without it.

02·After you connect

Ask. It lands.

You ask in Claude. Spera builds, compiles, and backtests the strategy in your account.

You ask

In Claude

Build an EMA 20/50 crossover on BTC/USDT 4h and backtest it.

It lands

Each step returns a receipt you can check, then opens in the builder. See a full run.

Never crosses: Deploy a bot · Read exchange keys · Move money. No tool for these exists on the server.

You describe a strategy in your AI app. It arrives in your Spera account as a real strategy — compiled, backtested, and documented, each step returning a receipt you can check. Bot deployment, exchange keys, and moving money never cross the connection, because no tool for them exists on the server.

03·What you grant

Ten permissions. None can trade.

These are the exact strings on the sign-in screen. Hold this page next to the dialog and check that they match.
