Connect Venmo to Codex

Use KosmoKrator as a local MCP proxy for Codex so coding sessions can reach selected integrations with explicit write policy.

Register kosmo mcp:serve as a local stdio server and choose the integration allowlist. The gateway is local, scoped to this integration, and starts with --write=deny so Codex can inspect read-capable tools without receiving write access by default.

Venmo MCP Config for Codex

Keep write access denied or ask-based unless the workspace is trusted.

  "mcpServers": {

        "mcp:serve",
        "--integration=venmo",
        "--write=deny"
      ]
    }
  }
}

Run the Gateway Manually

Why Use KosmoKrator Here
