Identity infrastructure.
Where your identity earns.

Start here

• alter CLI

  Install once. Pair every other surface as it ships. Requires Node.js >= 20. Then alter login to bind your ~handle. Arch Linux: yay -S truealter-cli.

  npm install -g @truealter/cli && alter login

• Any MCP client

  Drop ALTER into Claude Desktop, Cursor, Cline, Continue, Zed. One line, no install.

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

• TypeScript SDK

  Build on ALTER from your code. x402 retry, ES256 verify, DNS + well-known discovery.

  npm install @truealter/sdk

MCP

• POST mcp.truealter.com/api/v1/mcp

  Public JSON-RPC surface, L0–L5 pricing. Read tools open; messaging tools require per-peer grant.

• Claude Desktop config

  Add to ~/.config/Claude/claude_desktop_config.json (or %APPDATA%/Claude/ on Windows). Restart Claude.
