callsend 0.3.1

callsend — your agents call you. Voice supervision for background coding agents.

callsend

Your agents call you. callsend is voice supervision for background coding agents: when work lands — a task finishes, a PR fails, a decision is needed — your agent rings your phone or browser, briefs you out loud in a real duplex voice call, and takes your next instruction. Hang up and it ships.

This package is the local connector + MCP server:

• callsend — the CLI: callsend login (device pairing) and callsend connect (serve your local projects so calls can dispatch work to claude / codex on your machine).
• callsend-mcp — a stdio MCP server exposing a call_me tool to any MCP client (Claude Code, Codex, Cursor, …).

Zero-install alternative (recommended for call_me only)

You don't need this package just to let an agent ring you — use the hosted remote MCP endpoint instead (no code runs on your machine):

claude mcp add --transport http callsend https://api.callsend.dev/mcp

then /mcp in Claude Code to sign in. Install this package when you want the full connector: voice-dispatching work to agents on your own machine.

Install

uv tool install callsend        # or: pipx install callsend
callsend login                  # one-time approve link in the web app
claude mcp add callsend -- callsend-mcp

The mic is only live during a call you answered. Pairing scopes calls: an agent can only ever call its own human. Tokens are revocable from Settings.
