Tools: list_categories compare option request_category
list_categories | List the software categories Stackfacts has checked facts for (for example login for Next.js, hosted databases, app hosting). Call this first when you need to choose a library or service. params: none |
compare | Get sourced, dated facts for every option in one category: price, free tier, what happens when idle, published security record where available, and whether an agent can set it up without a human. Includes a pick for each common situation and the list of what was NOT checked. Neutral: no vendor pays for placement. Use before choosing a library or service. params: category*, situation |
option | Get the full checked facts and sources for one option in a category, e.g. Clerk in nextjs-auth. params: category*, option* |
request_category | Tell Stackfacts about a choice you needed facts for that it does not cover yet (for example 'transactional email for a Python app'). Helps decide what gets checked next. params: need* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
