steamgpt-mcp

MCP server for Steam data, backed by steamgpt.net - a free Steam data API for AI agents. Steam profiles, SteamID conversion, VAC / game / community / trade bans, FACEIT stats, public friend graph, batch lookups and player comparison. No API key, no registration, no tracking.

Registry name: net.steamgpt/steamgpt (official MCP Registry).

Quick start

The server runs remotely - the preferred setup is a direct Streamable HTTP connection, no install:

claude mcp add --transport http steamgpt https://steamgpt.net/mcp

Cursor (.cursor/mcp.json in a project, or ~/.cursor/mcp.json globally):

{ "mcpServers": { "steamgpt": { "url": "https://steamgpt.net/mcp" } } }

VS Code (Command Palette -> "MCP: Open User Configuration"):

{ "servers": { "steamgpt": { "type": "http", "url": "https://steamgpt.net/mcp" } } }

For clients that only support stdio servers, use this package as a proxy:

{ "mcpServers": { "steamgpt": { "command": "npx", "args": [ "-y", "steamgpt-mcp" ] } } }

The 8 tools

| Tool | What it answers | | --- | --- | | steam_identity | convert / resolve any SteamID form, vanity or profile link (fewest tokens) | | steam_bans | VAC, game, community and economy (trade) bans - first check for a cheating report | | steam_profile | raw Steam summary only (cheapest profile tool) | | steam_faceit | FACEIT player object: level, ELO, FACEIT bans | | steam_friends | public Steam friend graph (detail: short / medium / full) | | steam_summary | everything about one player; include trims the response | | steam_batch | up to 100 profiles in ONE call - always batch instead of per-player calls | | steam_compare | two players side by side + shared friends |

All tools are read-only and need no confirmation. Responses carry provenance (freshness) and sources/partial markers - branch on them, not on nulls.

Notes

• {id} accepts steamid64, STEAM_1:0:x, [U:1:x], a steamcommunity.com link or a vanity name.
• The HTTP API behind this server also answers in .md / .json / .ai formats: see steamgpt.net/ai and docs.
• Env override for the proxy: STEAMGPT_MCP_URL (default https://steamgpt.net/mcp).
• Fair use: soft limit 120 requests/min per IP; responses are cached.
