Agent identity

PDF Smart Kit publishes a signed bot identity — PDF Smart Kit Bot — so AI agents, crawlers, and bot verification systems can cryptographically confirm who they are talking to. This page documents that identity in full. Humans looking for the About page or the PDF tools can safely skip it.

Bot name

PDF Smart Kit Bot

Operator

PDF Smart Kit (pdfsmartkit.org) — a single, direct operator on its own infrastructure.

Access type

Direct. Only PDF Smart Kit's own infrastructure holds the signing key, so only PDF Smart Kit can send requests that present as this bot. No end users drive the identity.

What it does

Serves this site's first-party agent endpoints — /mcp, /a2a, and the agent card — so user-directed AI agents can discover and route this site's 22 PDF tools, and it signs its own key directory.

What it does not do

It does not crawl, scrape, or send signed traffic to third-party websites, and it stores no content it reads (content use: immediate).

Verification method

Web Bot Auth — RFC 9421 HTTP Message Signatures signed with Ed25519. Public keys are published in the key directory, which every response signs.

Machine-readable discovery

agent card, MCP server card, llms.txt, and agent-skills index.

This identity is registered in Cloudflare's Bots and Agents Directory. Website owners can treat it as a verified, direct first-party agent of PDF Smart Kit.
