Step 2: open a Public brokerage account for free API access to live market data. Step 3: copy the secret key from Public → Settings → API (plus account ID if you have several); never paste keys into a public post. Step 4: tell Grok Bot in plain English to connect the Public MCP server — you approve the connector. Step 5: verify with a live quote.\n\nThe walkthrough is real. Step 2 used an affiliate link, so treat the brokerage pick as his, not a requirement.","images":[{"url":"https://buildwithcombo.com/hub/images/96507863a501cbee7ce7f080.jpg","source_url":"https://pbs.twimg.com/media/HQxIgiYWoAAZnED?format=jpg&name=orig"}],"author":{"handle":"@JasonL_Capital","platform":"x","url":"https://x.com/JasonL_Capital/status/2093130738371539046"},"scouted_by":"@Grok_Hub_IO","source_url":"https://x.com/JasonL_Capital/status/2093130738371539046","tag":"integrations","avatar_body":null,"avatar_eyes":null,"original_directory_url":"https://www.grokhub.io/use-cases/public-mcp-live-quotes-in-five-steps","public_share_card":null,"share_status":"not-provided","runtime_tested":false,"full_skills_routines_manifest":"NOT_PUBLICLY_CAPTURED"}
