ISL MCP quickstart

Endpoint: https://mcp.innovationsyndicate.io/mcp. Authenticate with your ISL MCP key in the Authorization: Bearer header. Never put the key in a URL. Keys are issued by ISL under your partner agreement.

Credits work exactly like in the ISL web app. Every tool states its cost first. Paid tools run only when your user asks for that action, and each call must carry max_credits.
