bringfour

Give your AI assistant a competitive Pokémon brain. An MCP server (plus a local web dashboard) that turns Claude, Cursor, or any MCP client into a VGC teambuilding partner — real usage stats, real damage calcs, and threat reports grounded in math instead of type-chart guessing.

🚧 Pre-1.0: the npm publish is imminent — until it lands, use the from-source setup; everything works today.

Calc-backed threat report

Ask "what beats my trick room team?" and get back OHKO/2HKO lines computed with @smogon/calc against the top meta Pokémon at their actual most common spreads — not vibes. Defaults to the current official format (Pokémon Champions, Regulation Set M-B); SV Regulation I and other formats are one format parameter away.

Quick start

Claude Code

claude mcp add bringfour -- npx -y bringfour

Claude Desktop / Cursor

{
  "mcpServers": {
    "bringfour": {
      "command": "npx",
      "args": ["-y", "bringfour"]
    }
  }
}

From source

git clone <this repo> && cd <repo> && npm install

The repo ships a project-scoped .mcp.json, so Claude Code picks the server up automatically when working in this directory. For other clients, run npx tsx src/index.ts (stdio transport).

Tools

Tool	What it does
`meta_snapshot`	Top meta Pokemon with usage/win rates for a format.
`pokemon_deep_dive`	One Pokemon's common items, abilities, moves, spreads, natures, Tera types (SV), teammates.
`analyze_team`	Calc-backed threat report: for the top N meta Pokemon at their most common sets, real OHKO/2HKO threats against your actual EVs, plus speed tiers and speed-control flags (Tailwind/Trick Room/Icy Wind...).
`calc_damage`	Damage calc via `@smogon/calc`. Unspecified fields auto-fill from meta data; every assumption is echoed so the agent can override and re-call.
`save_team` / `list_teams`	Store Showdown-export pastes as plain text, so "analyze my worlds team" works without re-pasting.

Web dashboard

npm run ui        # http://localhost:4747

A local dashboard (dark, sprite-heavy, no build step) over the same data layer as the MCP tools:

Threats — pick a saved team, get the calc-backed threat report as cards with OHKO/2HKO badges, damage bars, a speed ladder, and speed-control flags.
Damage Calc — attacker/defender panels that pre-fill the most common meta set (grayed-italic until you override a field), live results, field conditions, swap sides.
Teams — create/edit Showdown pastes, or import from a pokepast.es link.
Meta / deep-dive — sortable usage table; click through to per-Pokemon items, moves, spreads, natures, and teammates.

Where data lives

Running from a checkout (or any directory containing a teams/ folder) keeps teams in ./teams/ and the 24h usage-data cache in ./.cache/, as always. Running via npx/global install falls back to ~/.bringfour/. Override with:

Env var	Effect
`VGC_TOOLS_HOME`	Base directory for both (`<home>/teams`, `<home>/cache`)
`VGC_TEAMS_DIR`	Teams directory only
`VGC_CACHE_DIR`	Cache directory only

Data sources & behavior

Pikalytics (pikalytics.com) is the primary usage source — in-game ranked battle data for Champions, HOME battle data for SV. Pikalytics asks for attribution when citing its stats; every tool response carries it.
Smogon usage stats (smogon.com/stats, Showdown ladder chaos JSON) are the automatic fallback when Pikalytics lacks a format.
Usage dumps are monthly; the service walks back up to 7 months to find the newest published data, and caches responses for 24h.
Teams are plain Showdown-export text files — edit them freely.

Champions caveats (honest-approximation zone)

Champions EVs run 0–32 per stat. For damage/stat math they are mapped onto the classic 0–252 scale (×8, capped); every calc that does this says so in its assumptions. Treat very close rolls with caution.
Champions Mega formes ("Charizard-Mega-Y") mostly exist in @smogon/calc's data already; anything the calc doesn't know is reported explicitly instead of guessed at.

Roadmap

v2: EV-spread optimization; tournament results/team lists via the documented Limitless API.
Hosted copilot: a web app where a frontier model writes full team coaching reports over these tools — in design, gated on this repo proving demand. Star the repo if you want it to exist.

Support

If this saves you a ladder session of scouting, a star is the best signal you can send.
