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.
These clients handle login for you: paste the server URL, sign in to Talismos when prompted, approve the connection, and an API key is created and wired in automatically. Nothing to copy or paste.
Generate an API key from your dashboard and set it as a Bearer token yourself (the same key you'd use for the REST API). Every tool call counts against that account's plan quota exactly like a direct API call would, regardless of which path you used to connect.

Both tools require an exact birth date, time, and location — the connected agent will ask for anything missing rather than guess.
Full natal chart, same data as POST /v1/birth-chart.
Input: Birth date, time, latitude/longitude, plus optional house system, zodiac, and language.
Output: Planets, points, angles, houses, and aspects as structured JSON.
The same chart formatted for conversation, same data as POST /v1/chart-context.
Input: Same fields as calculate_birth_chart.
Output: The chart as prose and markdown, ready to use directly as context in the conversation.
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.”
