~alter Identity MCP MCP server

The ~alter Identity MCP server exposes identity infrastructure through the Model Context Protocol, allowing AI agents to verify identities, extract traits, compute Belonging Probability, and transact with human identity data. It supports 47 tools, including free verification and paid queries using the x402 micropayment protocol, with 75% of payments going to the data subject.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http alter-identity-mcp https://mcp.truealter.com/api/v1/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add alter-identity-mcp --url https://mcp.truealter.com/api/v1/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable alter-identity-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "alter-identity-mcp": {
      "url": "https://mcp.truealter.com/api/v1/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "alter-identity-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.truealter.com/api/v1/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start alter-identity-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "alter-identity-mcp": {
      "type": "http",
      "url": "https://mcp.truealter.com/api/v1/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http alter-identity-mcp https://mcp.truealter.com/api/v1/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "alter-identity-mcp": {
      "url": "https://mcp.truealter.com/api/v1/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "alter-identity-mcp": {
      "serverUrl": "https://mcp.truealter.com/api/v1/mcp"
    }
  }
}
