When to use MCP (and when not) – with Gus Pelogia (Indeed) | Ep.269

Live from brightonSEO: Björn talks with Gus Pelogia, Product Manager at Indeed and advocate for product-led SEO, about his talk “When to use MCP and when not to use MCP”.
Gus explains why the real value of MCP comes from connecting several tools in a single flow: keyword research, People Also Ask data, prompt tracking and leadership reporting, all from one Claude conversation without exporting files. He walks through a practical example: clustering 4,000 headphone keywords into brand, feature and price buckets in minutes, then turning them into prompts for AI visibility tracking.
The episode also covers where MCP falls short. Gus explains why 15 parallel SERP checks are better handled by a script written with Claude Code, why MCP results can differ from API data, and how he checks whether outputs are accurate. Other topics include agents replacing website visits, the “death of the web” debate, and why you should never trust the numbers blindly.
Key Takeaways
• MCP is strongest when it connects multiple tools in one workflow. Research, analysis, charts and reporting stay in one place.
• Setup is easy: add the connector, log in to the tool, and start asking. You don’t need prompt engineering, just talk to it like an assistant.
• Main KPI is time saved. Research that used to take a day now takes about 30 minutes.
• Don’t use MCP for repetitive, large-scale jobs like live results for 15 cities. Have Claude Code write a script instead.
• MCP does not always match API data, and token costs can add up quickly with complex tasks.
• Daily monitoring (robots.txt changes, page-type update checks) still runs on scripts and Google Sheets, not MCP.
• To build trust in results, ask the model to verify its own data and explain how it checked.
• Agents will reduce website visits, but websites remain the source of truth for validation.
