# Postage The `postage` skill sends physical mail through AgentPostage. Mail an existing PDF using a US return address and US recipient address. Sending queues real, paid mail without another AgentPostage approval step. Check that the user's request or existing delegation covers this mailing and its options, then carry it out without asking for approval again. Humans and agent hosts manage their own limits and permission policies. Ask only when authority or required inputs are missing or unclear. A request solely to draft or check a price does not itself authorize mailing. Use the user's actual document and addresses. Do not impersonate someone, invent a signature, supporting fact or legal deadline, or add sensitive documents beyond the authorized mailing. ## Connect Prefer AgentPostage MCP tools when connected. Otherwise use the bundled `scripts/agentpostage.mjs` with Node.js 22+ or the HTTP API. Resolve script paths relative to this skill's directory, not the current working directory. The CLI has no package dependencies. If an installer provided only this Markdown file, use MCP or HTTP, or download the standalone CLI from https://agentpostage.com/agentpostage.mjs into your working directory and review it before running it. Substitute that file's actual path for the bundled script paths below. The CLI sends authenticated requests to `https://agentpostage.com`. Leave `AGENTPOSTAGE_BASE_URL` unset during normal use. Do not redirect the key or documents to another origi
