Talismos runs an MCP (Model Context Protocol) server — a live connection any MCP-compatible AI agent (Claude, n8n, and others) can use to call the real chart engine directly, inside a conversation.
This isn't a prompt or a set of instructions you paste into a chat. It's a real server your AI client connects to over HTTP: it authenticates once with your API key, then the client itself discovers and calls the available tools — the model decides when to use them, but the calculation always runs on Talismos's real engine, not a guess.
Use one of your Talismos API keys as a Bearer token — the same key you already use for the REST API. Generate one from your dashboard if you don't have one yet. Every tool call counts against that account's plan quota exactly like a direct API call would.

Open Settings → Connectors → Add → "Add custom connector", paste the server URL below, and complete authentication when prompted. If your version instead expects a config file, add an entry under "mcpServers" with this url and an Authorization: Bearer header carrying your API key.
Settings → Connectors → Add → "Add custom connector" → paste the URL below and click Add. Claude.ai handles the login automatically (OAuth) — you don't need to paste an API key here at all.
Add an "MCP Client" node, set the Server URL to the address below, and set the Authorization header to Bearer followed by your API key.
Full natal chart: planets, points, angles, houses, and aspects — same data as POST /v1/birth-chart.
The same chart, formatted as prose and markdown ready to use as conversation context — same data as POST /v1/chart-context.
Once connected, you can just ask in plain language — the agent will ask you for anything it's missing (exact birth date, time, and location) before calculating.
“Calculate my birth chart — I was born October 10, 1995, at 2:30 PM in Florianópolis, Brazil.” “What's my Sun sign and Ascendant?” “Give me my chart as something you can use as context for the rest of this conversation.”
