Questions that work

  • What sites launched in the UK with WordPress this week, only ones with a contact email?

  • What is example.com built with?

  • Which analytics tools are growing fastest this quarter?

  • Watch for new Shopify launches in Germany and email me daily.

                      Runs on your StackScope Data plan, the same as the API.

The address

URL

https://mcp.stackscope.dev

Sign in and approve access the first time. Disconnect any time from API keys.

i

                    Command-line tools and editors receive the sign-in callback on your own
                    machine. Keep the app running while you approve, or the browser will show
                    a connection error at `127.0.0.1`.

Claude and ChatGPT

Settings, then connectors, then add a custom connector. Paste the address.

What it costs

The same as the API, because it is the API. One credit per call, and one site from your monthly allowance for each site returned to you for the first time this period. Repeats are free.

                    Before a large result, StackScope tells your assistant what it will cost
                    and waits for you to approve it:

i

                    This returns 240 sites, all new to you this period. It costs 1 credit and
                    240 of the 2,847 sites left in your allowance this period. Go ahead?

Nothing is charged unless you say yes. Small calls do not interrupt you, and account_status reports what is left for free.

What your assistant can do

account_status

Plan, permissions and remaining allowance. Free.
