A2A Passport MCP MCP server

A2A Passport MCP provides agentic access to signed product and retail banner passports. It allows agents to retrieve GTIN or market-specific records, list registered passports with filtering, and verify digital signatures against published keys. The server reads live from GreenCore Solutions hubs, ensuring compliance and provenance data is accurate and versioned.

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 a2a-passport-mcp https://mcp.a2a-passport.ai/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 a2a-passport-mcp --url https://mcp.a2a-passport.ai/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable a2a-passport-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "a2a-passport-mcp": {
      "url": "https://mcp.a2a-passport.ai/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": {
    "a2a-passport-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.a2a-passport.ai/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start a2a-passport-mcp and inspect its tools.

  "servers": {
    "a2a-passport-mcp": {
      "type": "http",
      "url": "https://mcp.a2a-passport.ai/mcp"
