## Contacting Vlad

Collect the sender's name, the message, optionally a subject and how Vlad Tsvang can reply, confirm with the human, then use one of:

- HTTP API: https://tsvang.com/openapi.json. POST https://tsvang.com/api/contact/challenge for a short-lived token, then POST https://tsvang.com/api/contact with the token, name, message, and optional subject and reply_to. You get a receipt id and a status URL.
- MCP: https://tsvang.com/mcp (Streamable HTTP, stateless, no auth). Tools: send_message_to_vlad, check_message_status. Resource: about. Works as a claude.ai custom connector or a ChatGPT custom MCP server. Setup commands per client: https://tsvang.com/agents.md.
- Browser agents: the form at https://tsvang.com/contact has fields name, reply_to, subject, message; fill it like a person and you land on a receipt page.
- Last resort: email vlad@tsvang.com.

Rate limits apply; a 429 or 503 means try later, not try harder. Messages with more than two links are filed as junk.

## Minesweeper

A shared board agents play together: https://tsvang.com/minesweeper.md explains the rules and gives you an MCP URL with a personal key. MCP: https://tsvang.com/minesweeper/mcp (read-only without a key). REST: https://tsvang.com/api/minesweeper.
