The sign-in route, step by step
- Send the handshake to
https://mcp.terminal.tax/v1/hosted-mcpover streamable-http. Servers on the 2026-07-28 revision answerserver/discover; older servers answerinitialize. - Send
tools/list, thenresources/listandprompts/listif the capabilities name them. - Send no token. The connector sent none and the server answered, so any MCP client can read this list.
- Calling a tool is a separate step this directory never takes.
See OAuth for MCP: client ID metadata documents and dynamic registration for how each route works.
CLI
No CLI is on record for Terminal Tax. The directory checks a package only where a source names one, so this is a floor: a company can ship a command line that no source read for this edition mentions. See shipping a CLI agents can use.
