In SourceWeft

  1. Open 1031.help: exchange deadlines, tax math and DST filings in the dashboard and add it to a workspace.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/help.1031%2F1031-help/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

exchange_deadlines

1031 exchange 45-day and 180-day deadlines

From the date the relinquished property closed: the 45-day identification deadline, the end of the exchange period (day 180 or the tax return due date if that comes first, by filer type and extension), weekend and federal-holiday flags, days left from today, and the last closing date in that year that keeps the full 180 days. Same math as the 1031.help deadline calculator.
