Roblox MCP server

@pipeworx/roblox

Roblox MCP — keyless public-profile lookups via roblox.com's subdomain APIs.

Part of Pipeworx — an MCP gateway connecting AI agents to 1679+ live data sources.

Tools

• userbyusername(username) — resolve username → user id
• user(user_id) — user profile detail
• userfriends(userid) — friends list
• userfollowerscount(user_id) — follower count
• userfollowingscount(user_id) — following count
• userbadges(userid, limit?, sortOrder?) — badges
• usergames(userid, limit?, sortOrder?) — created games
• userpresence(userids) — presence/status for up to 100 user ids (POST)
• group(group_id) — group detail
• game(universe_id) — game (universe) detail
• gamepasses(universeid? | placeid? | name?, cursor?, limit?) — list the game passes sold in an experience with their exact Robux price. Pass exactly one of universeid, placeid, or name (e.g. "Grow a Garden") to resolve the experience. A pass currently not for sale returns isforsale: false and pricerobux: null (never 0). Cursor-paginated, capped at 100 per page. Note: many top experiences monetize through consumable "developer products" rather than permanent game passes, so a short or empty list can be the correct answer, not a broken call.

Data source

https://users.roblox.com, https://friends.roblox.com, https://badges.roblox.com, https://games.roblox.com, https://groups.roblox.com, https://presence.roblox.com, https://apis.roblox.com (game-passes, universes, search-api)

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "roblox": {
      "url": "https://gateway.pipeworx.io/roblox/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/roblox/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — askpipeworx, discovertools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1679+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/user_by_username \
  -H 'Content-Type: application/json' \
  -d '{"username":"builderman"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/userbyusername. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "roblox": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-roblox"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-roblox
