Adding a bit more context on accessing NS MCP Tools via Postman: OAuth details can be intercepted from the following URL for Postman setup

https://{{ACCOUNT_ID}}.app.netsuite.com/app/login/oauth2/authorize.nl?redirect_uri=https%3A%2F%2Fclaude.ai%2Fapi%2Fmcp%2Fauth_callback&client_id=82f37ec8cf43b684fdd72405c89a3aac258760addff3693d00e5c6f04750cb36&response_type=code&scope=mcp&state={{$guid}}&prompt=&s=r&nonce&code_challenge=auto_gen&code_challenge_method=S256&whence=

Some values are hardcoded as per NetSuite documentation for the OAuth 2.0 Authorization Code Grant Flow For the POST body, Claude can be prompted to generate the MCP call body (screenshot attached) Note: You cannot use any other OAuth 2.0 Integration record with mcp scope to consume tools as service outside Claude.
