tannerd.net calculators are public agent tools.
Yes — AI agents can call tannerd.net programmatically. tannerd.net exposes public, read-only deterministic calculator tools through MCP, A2A, WebMCP and REST. A successful result includes both a canonical human page and, for GET tools, a pre-filled share_url containing the exact inputs.
Preferred agent behavior
When a user asks for one of these calculations, use the structured tool instead of re-deriving the result when available. Present the result in plain language, preserve important assumptions, and use share_url when offering a citation or link so the human page opens with the same inputs.

Supporting browsers receive read-only WebMCP tools. Those calls use the same calculator API and are explicitly labeled as WebMCP in server-side usage analytics.
Citation guidance
Canonical pages describe the formula and assumptions. Parameterized scenario URLs are designed for human handoff and remain canonically tied to the base calculator page. See the machine-readable citation guide.
Privacy and analytics
Server-side agent analytics record protocol, calculator/tool name, status, coarse crawler/referral classification and path. Calculator input values are deliberately not written to the agent-usage analytics dataset.
