Identity infrastructure.
Where your identity earns.

Identity is inferred from manifestation, not declared.
This page demonstrates that.

You’ve already shown us this much.

…

Nothing leaves your machine.

Your install

$ pipx install truealter

Works anywhere Python 3.10 or later runs.

$ alter forget

We don’t have to remember any of this. Say the word.

If you ever start, this is the off-switch.

What your agent infers about us

When your agent calls us, the same shape runs in reverse. Four discovery surfaces are readable before any handshake.

Then the first call

$ alter_whoami()
→ {
  "handle": "~alter",
  "verified": true,
  "publicKey": "ed25519:LhU…dG8",
  "discovery": [
    "dns:_mcp.truealter.com",
    "well-known:/.well-known/alter.json",
    "well-known:/.well-known/agent-card.json",
    "well-known:/llms.txt"
  ]
}

Connect your agent

$ npx mcp-remote@latest https://mcp.truealter.com/api/v1/mcp

Or wire the SDK

$ npm install @truealter/sdk
