RMTHub MCP Server
Connect your AI agent to RMTHub. Query FunPay, G2G, Playerok, and Eldorado stats — leaderboards, market indexes, and seller analytics — right inside Claude, ChatGPT, Cursor, Codex, and any MCP-compatible tool.
What is MCP?
Model Context Protocol (MCP) is an open standard that lets AI tools call external services. RMTHub exposes marketplace analytics as MCP tools so assistants answer with live data instead of guesses.
What you can ask
FunPay, G2G, Playerok & Eldorado
One MCP server covers every RMTHub marketplace — parallel tools for stats, leaderboards, sellers, and market data on each platform.
Leaderboards, stats & market indexes
Top games, top sellers, platform-wide metrics, price rollups, and market indexes — the same data as the hub pages, formatted for agents.
Secure OAuth access
Sign in with your RMTHub account. Tokens are short-lived; no API keys pasted into chat.
Tier-aware responses
Free Common tier includes core tools; Rare and Mythic unlock deeper leaderboard ranks and fuller tool responses.
How it works
Pick your AI agent below and add the RMTHub MCP server URL.
Your client discovers OAuth endpoints on rmthub.com and opens a browser sign-in.
After you approve, the client receives a Bearer token scoped to MCP tools.
Tool calls go to the MCP resource server; responses respect your subscription tier.
Set up the RMTHub MCP Server
Works in Claude (Web, Desktop, Code), ChatGPT, Cursor (App, CLI), Codex (App, CLI), and any other MCP-compatible agent. RMTHub MCP Server is hosted at https://mcp.rmtchat.com/mcp, so there's no local install. Authentication uses OAuth 2.1 with dynamic client registration. Pick your agent below, add the server URL, and log in to RMTHub in the browser window that opens. Your credentials are stored and refreshed automatically.
Server URL
https://mcp.rmtchat.com/mcp
Run this command in your terminal:
claude mcp add --transport http rmthub https://mcp.rmtchat.com/mcp
Then open a Claude Code session and run /mcp to complete the OAuth login flow.
Custom MCP connectors require Developer Mode and a paid ChatGPT plan.
In ChatGPT, go to Settings → Plugins → Developer Mode and toggle Developer Mode on.
In Plugins, click (+) to add a custom plugin.
Enter: Name: RMTHub · Server URL: https://mcp.rmtchat.com/mcp · Authentication: OAuth
Click Create.
Click Sign in. ChatGPT will open a browser window. Log in to RMTHub and authorize the connection.
Plan requirements: Custom MCP connectors are available on Plus, Pro, Team, Business, and Enterprise plans. Developer Mode must be enabled first.
Model effort requirement: Reasoning effort set to Medium or High. Set this in the model picker (Model → Effort). Instant does not support MCP tool calls.
Note for Business and Enterprise plans: A workspace admin or owner must enable Developer Mode in Workspace Settings → Permissions & Roles → Connected Data before members can add custom plugins.
The Codex plugin and CLI share the same ~/.codex/config.toml file, so setup is identical for both.
Option A: CLI command
codex mcp add rmthub --url https://mcp.rmtchat.com/mcp
Option B: Edit config directly
Open ~/.codex/config.toml and add:
[features] experimental_use_rmcp_client = true [mcp_servers.rmthub] url = "https://mcp.rmtchat.com/mcp"
Then log in:
codex mcp login rmthub
To verify the connection, open Codex and run /mcp.
Via the Settings UI
Open Cursor Settings → Tools & MCP → New MCP Server.
In the mcp.json file that opens, add the following under mcpServers:
Save the file. Cursor will show the server in the MCP panel with a Needs login status.
Click Needs login and complete the OAuth flow in your browser.
{
"mcpServers": {
"rmthub": {
"url": "https://mcp.rmtchat.com/mcp"
}
}
}Via config file
Edit ~/.cursor/mcp.json (global, all projects) or .cursor/mcp.json in a project folder (project-scoped) with the same JSON block below.
Save and toggle the server off/on in Settings → Tools & MCP to reload without restarting.
Authenticate by clicking Needs login in the panel.
{
"mcpServers": {
"rmthub": {
"url": "https://mcp.rmtchat.com/mcp"
}
}
}Any agent that supports remote MCP servers with OAuth can connect using the server URL below. Refer to your agent's documentation for how to add a remote MCP server.

Access & tiers
MCP tools mirror site data. Some ranks and marketplaces require an active Rare or Mythic subscription. Free accounts still get useful summaries and top-level stats.
FAQ
Yes. RMTHub MCP is maintained by RMTHub and uses the same data as the website and public API.
Connecting is free. Tool responses follow your RMTHub subscription: Common (free) includes core tools; Rare and Mythic unlock deeper leaderboard ranks and fuller tool responses.
Any client that supports remote MCP over HTTPS with OAuth — including Claude (Web, Desktop, Code), ChatGPT, Cursor (App, CLI), Codex (App, CLI), and other MCP-compatible products.
RMTHub is the OAuth authorization server (https://rmthub.com). Your MCP client registers dynamically, opens a browser login, and receives a short-lived access token. The MCP resource server validates that token on every tool call.
No API keys are required for MCP — OAuth handles access. Your chat history stays in your AI client. RMTHub logs MCP tool calls for security and analytics but does not receive your conversation text.
Only marketplace analytics exposed through RMTHub MCP tools, scoped to your account tier. The connector cannot access data outside your RMTHub subscription entitlements.
Disconnect or remove the RMTHub MCP server in your AI client. Access tokens expire within an hour; disconnecting stops new tool calls immediately.
Disconnect RMTHub in your client, reload MCP servers, and connect again. Ensure you sign in with the RMTHub account you intend to use. If the error persists, confirm the server URL is exactly https://mcp.rmtchat.com/mcp.
Use the exact URL https://mcp.rmtchat.com/mcp. Some agents require a restart or MCP reload after adding a server. Check your client's MCP status panel (/mcp in Claude Code or Codex, Settings → Tools & MCP in Cursor).
Rare and Mythic tiers unlock deeper leaderboard ranks and extra marketplaces. When your tier limits a field, tools return a subscribeUrl pointing to rmthub.com instead of gated data.
Yes. Run chat/mcp locally (default http://127.0.0.1:8010/mcp) and point your client at that URL. Your local frontend OAuth issuer should match NEXTAUTH_URL (e.g. http://localhost:3003).
If your agent supports remote MCP servers with OAuth, add URL https://mcp.rmtchat.com/mcp manually. Most modern MCP clients follow the same HTTP + OAuth flow described in the Other section.
