steamwebapi is a remote MCP server that gives an AI agent 11 tools, among them call_readonly_endpoint, get_concept, get_endpoint. It answers at https://mcp.steamwebapi.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 24 October 2026, succeeded.

Description as the publisher wrote it.
| Tool | What it does |
|---|---|
call_readonly_endpoint | 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. Inputs: path, parameters, timeoutMs, maxResponseBytes |
get_concept | 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. Inputs: term |
get_endpoint | 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. Inputs: path, method |
get_integration_skill | Read the reusable SteamWebAPI SKILL.md for integration workflows, credentials, prices, item variants and CS2 release discovery. Useful when the client does not expose MCP resources or initialization instructions. |
get_pricing | 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. Inputs: useCase, expectedRequestsPerDay, includePlanCatalog |
list_concepts | Lists every curated concept exposed by get_concept, optionally filtered by category. Use to discover what domain explanations are available. Inputs: category |
list_endpoints | Lists all steamwebapi.com endpoints (path + method + summary), optionally filtered by tag. Useful for quickly enumerating what is available. Inputs: tag |
list_games | Lists every game supported by steamwebapi.com with its slug, name, Steam appId, and the value to pass as `game=` in API queries. |
list_markets | Lists every third-party marketplace covered by the steamwebapi.com market price endpoints, with their domain and the games they cover. Inputs: game |
list_products | Lists steamwebapi.com product packages (Price API, Inventory API, Float API, ...) with the endpoints each one bundles. Use get_pricing for paid plans, request quotas and upgrade guidance. |
search_endpoints | Fuzzy text search across all steamwebapi.com OpenAPI endpoints and Steam domain concepts (assetid, doppler phase, market_hash_name, etc.). Returns ranked hits with path, method, tag and summary. Inputs: query, kind, tag, limit |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.steamwebapi.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
