MetaBot.GG for AI Agents

What you can access

MetaBot.GG aggregates real-match statistics for League of Legends, Teamfight Tactics, Valorant, Deadlock, Marvel Rivals, Counter-Strike 2 and Slay the Spire 2. Every tier list, win rate, pick rate, build, matchup and team comp is computed from actual games and refreshed each patch.

It is the same data you find across the site. For how it is collected and computed, see our data methodology.

Connect to the MCP server

The server speaks the Model Context Protocol over streamable HTTP. It is public and read-only, so no API key, account or auth flow is required — just point your client at the endpoint below.

• Endpointhttps://metabot.gg/api/mcp
• TransportStreamable HTTP (Model Context Protocol)
• AuthenticationNone — public and read-only
• Rate limitsYes — about 60 requests/minute per IP, plus an overall ceiling across all callers

Claude Desktop and other stdio-only clients

Clients that only speak stdio can reach the remote server through the mcp-remote bridge. Add this to your client config (for example claude_desktop_config.json) and restart the client:

{
  "mcpServers": {
    "metabot-gg": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://metabot.gg/api/mcp"]
    }
  }
}

Clients with native remote MCP support

Clients that support remote HTTP MCP servers directly (many IDEs and agent frameworks) can register the endpoint without a bridge:

{
  "mcpServers": {
    "metabot-gg": {
      "type": "streamable-http",
      "url": "https://metabot.gg/api/mcp"
    }
  }
}

What you can ask (tools)

The server exposes nine read-only tools. Each returns a short text answer, structured JSON, and a link to the relevant metabot.gg page.

• lookup_game_entity — Current stats for a single champion, agent, hero, weapon, card or relic. Example: "Is Jinx good right now?"
• get_game_meta — Tier list / meta snapshot, optionally filtered by role, class or map. Example: "Best League junglers this patch."
• compare_game_entities — Head-to-head matchup, counter or synergy between two entities. Example: "Does Garen beat Darius?"
• get_entity_build — Recommended runes and items build (League, TFT, Deadlock). Example: "Best build for Haze."
• get_counters — Hardest matchups and counter picks (League, Valorant, Deadlock, Marvel Rivals). Example: "What counters Darius?"
• get_synergies — Best duos and partners (League, TFT, Valorant, Deadlock, Marvel Rivals). Example: "Who works well with Lucian?"
• get_team_comp — Best team compositions (TFT, Valorant, Marvel Rivals, Deadlock). Example: "Best TFT comps this patch."
• whats_trending — This patch's risers, fallers and hottest picks. Example: "Who got buffed in League?"
• list_supported_games — Lists every game MetaBot.GG covers, with example questions and links.

Rate limits & fair use

To keep the server fast and free for everyone, requests are rate limited — capped per client IP (about 60 requests per minute) and by an overall ceiling across all callers. Normal agent usage, answering a question with a handful of tool calls, stays comfortably within these limits.

If you exceed a limit, the server responds with HTTP 429 (Too Many Requests) and a Retry-After header giving the number of seconds to wait. Honor it: pause and retry after that delay instead of retrying immediately. If you have a legitimate high-volume use case, contact us before scaling up so we can help.

The widget and backlink

Every tool result includes a link to the specific metabot.gg page for that answer. Clients that render MCP UI show a compact MetaBot.GG card with a call-to-action button; other clients receive the same link in the tool's text and structured output.

When you present MetaBot.GG data to a user, surface that link so they can open the full, always-current breakdown.
