Rgl

MCP server that wraps the RGL API with natural-language tools. Designed for hosting on fly.io.

What it does

Translates queries like "every player who played IM in S7 of 6s" into the right sequence of API calls:

1. Resolves "6s" → format/region (defaults to NA when not specified).
2. Resolves "S7" → SeasonId by fuzzy-matching cached season list.
3. Resolves "IM" → DivisionId scoped to the region.
4. Fetches the corresponding Group, then its rosters.
5. Optionally bulk-fetches profile data for every unique player.

Tools

Tool	Purpose
find_season	Resolve season phrase → SeasonId
find_region	Resolve region phrase → RegionId
find_division	Resolve division phrase → DivisionId (scoped to a region)
find_team	Substring search on team name/tag

Local development

npm install
npm run dev

The server reads .env.local for RGL_API_BASE_URL etc. By default it points at the production RGL API.

Deploy

fly launch --name rgl-mcp --copy-config --no-deploy   # first time only
fly deploy

Then point your MCP client at https://rgl-mcp.fly.dev/mcp (Streamable HTTP transport).
