What this MCP does

Provides sourced, dated comparisons and facts about software options, pricing, security records, and setup requirements.

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.
Input schema
{'type': 'object', 'required': ['category'], 'properties': {'category': {'type': 'string', 'description': 'Category id from list_categories, e.g. nextjs-auth'}, 'situation': {'type': 'string', 'description': 'Optional. One sentence on what you are building and your constraints. Recorded so missing categories and facts can be added; does not change the answer.'}}, 'additionalProperties': False}
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.
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
option
Get the full checked facts and sources for one option in a category, e.g. Clerk in nextjs-auth.
Input schema
{'type': 'object', 'required': ['category', 'option'], 'properties': {'option': {'type': 'string', 'description': 'Option id or name, e.g. clerk'}, 'category': {'type': 'string'}}, 'additionalProperties': False}
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.
Input schema
{'type': 'object', 'required': ['need'], 'properties': {'need': {'type': 'string'}}, 'additionalProperties': False}
