About Roblox
Roblox is an MCP server for querying public Roblox data, intended for workflows involving user, group, and game information. It requires no key and supports lookups for friends, badges, presence, and game pass prices.
Key features
- 01Resolve usernames and retrieve user profiles
- 02Query friends, follow counts, and presence
- 03View badges and created games
- 04Look up groups, games, and game pass prices
Use cases
- 01Verify a Roblox user's profile and identity
- 02Check a user's friends, follow counts, or presence
- 03Find games created by a user and their badges
- 04Check game pass prices for an experience
MCP support
Exposes Roblox public-profile lookup tools to MCP clients through the Pipeworx gateway or as a local stdio MCP server. The gateway endpoint also provides shared meta-tools.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

From the project README@pipeworx/roblox
Roblox MCP — keyless public-profile lookups via roblox.com's subdomain APIs.
Part of Pipeworx — an MCP gateway connecting AI agents to 1683+ live data sources.
Tools
user_by_username(username)— resolve username → user iduser(user_id)— user profile detailuser_friends(user_id)— friends listuser_followers_count(user_id)— follower countuser_followings_count(user_id)— following countuser_badges(user_id, limit?, sortOrder?)— badgesuser_games(user_id, limit?, sortOrder?)— created gamesuser_presence(user_ids)— presence/status for up to 100 user ids (POST)group(group_id)— group detailgame(universe_id)— game (universe) detailgame_passes(universe_id? | place_id? | name?, cursor?, limit?)— list the game passes sold in an experience with their exact Robux price. Pass exactly one ofuniverse_id,place_id, orname(e.g."Grow a Garden") to resolve the experience. A pass currently not for sale returnsis_for_sale: falseandprice_robux: null(never0). 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 — ask_pipeworx,
discover_tools, 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 1683+ 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/user_by_username. 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
It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call
for only this pack's tools — none of the shared meta-tools the gateway
connection above adds. Same source, same tools, no ask_pipeworx routing.
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Roblox data" })
The gateway picks the right tool and fills the arguments automatically.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
