~Alter
This connects AI agents to TrueAlter's psychometric identity verification system, letting you confirm you're talking to a verified human rather than another bot. It exposes identity queries over MCP with x402 micropayment integration, so agents can programmatically verify identities during interactions. You'd reach for this when building AI systems that need to distinguish between human and AI participants, or when you need cryptographic proof of human identity in agent workflows. The streamable HTTP transport makes it straightforward to integrate, and the micropayment model means you pay per verification rather than maintaining subscriptions.

Install
From registry metadata$ npx add-mcp https://mcp.truealter.com/api/v1/mcp --name identity --header 'X-ALTER-API-Key: ${X_ALTER_API_KEY}'Run in your terminal. add-mcp asks which agents to add it to, then asks for each value it needs. Add -g to install it for every project.
Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

What is ~alter?
Run alter register, choose a name and confirm you are eighteen or older. Your
own machine spends a few seconds proving there is a person behind the request,
and then ~yourname exists.
