FAQ

Can the playground connect to local STDIO MCP servers?
No. STDIO servers require the Postman Desktop app because they execute local commands.
Can I inspect MCP OAuth flows here?
You can authorize remote MCP servers with OAuth 2.0 here. Advanced OAuth settings are available in the Postman Desktop app.
Does the playground save MCP requests?
It can hand off the current request during sign-up so it can be saved in Postman.
