What this server can do

10 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

call_readonly_endpoint(path, timeoutMs, parameters, maxResponseBytes)
Executes a documented steamwebapi GET endpoint with the caller API key from the MCP Authorization or X-Api-Key header. Refuses POST/PUT/PATCH/DELETE plus Proxy, Steam Guard and Tradeoffer endpoints. Required: path.
get_concept(term)
Returns a detailed explanation for a Steam / steamwebapi concept (identifiers, CS2 mechanics, pricing fields, inventory flags). Built from curated domain knowledge specific to this platform. Required: term.
get_endpoint(path, method)
Returns the full OpenAPI operation object for a given path: parameters, request body, all response schemas, examples, and tags. Use after search_endpoints to drill into a specific endpoint. Required: path.
get_pricing(useCase, includePlanCatalog, expectedRequestsPerDay)
Returns public steamwebapi pricing plans, per-endpoint rate limits, API-key location, quota guidance and a recommended plan for the requested use case. Does not perform checkout or account actions.
list_concepts(category)
Lists every curated concept exposed by get_concept, optionally filtered by category. Use to discover what domain explanations are available.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
