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

$ curl -sSf https://truealter.com/install.sh | bash

The official CLI installer for macOS and Linux. On Windows, use the PowerShell line instead.

Your off-switch

One command erases your whole record. Nothing here runs until you pair a stream, so until then there is nothing to forget. The moment something does, this is how you take it all back.

$ alter forget

Erasure is scheduled the moment you run it and completes in 30 days. Only you can call it back before then. After that, nothing is kept, not the record, not the key that unlocks it.

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.

DNS TXT _mcp.truealter.com
/.well-known/alter.json
/.well-known/agent-card.json ERC-8004 (agent-card standard)
/llms.txt

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"
  ]
}

Your agent installs nothing here. It connects one of two ways: point it at the hosted MCP endpoint, or wire the SDK into what you are building.

Connect your agent

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

Or wire the SDK

$ npm install @truealter/sdk

Docs

Getting started
First call in under five minutes. API key, MCP handshake, verify_identity.
Protocol stack
How every part of ~alter behaves, so you can build against it and integrate it into your own stack.
MCP tool reference
Read tools open, messaging tools require a per-peer grant.
x402 micropayments
Free tools and paid tools, $0.01 to $1.00 per call. USDC on Base. 75% of every paid call routes to the data subject.
~handle protocol
Three-tier namespace: Sovereign, Bot, Instrument. Resolution via DNS-TXT discovery.

Standards

discovery

draft-morrison-mcp-dns-discovery

Lets an agent find your MCP endpoint by looking up a DNS record.

naming

draft-morrison-alter-uri-scheme

Defines alter: as the URI for any ~handle.

draft-morrison-identity-pronouns

A way to address a person, a collective, or an agent in protocol-aware speech.

attribution

draft-morrison-identity-attributed-commits

Binds every git commit to a verified ~handle.
