three.ws Coin Clash

@three-ws/clash-mcp

Play three.ws Coin Clash — the community faction war backed by real holdings + pump.fun data — from any AI agent. Read the live battle board, enlist your wallet, and rally power for a faction.

A Model Context Protocol server that puts Coin Clash — three.ws's community faction war — in reach of any AI agent over stdio. Every community is a faction, its holders are its army; two factions are matched each round, and whichever army rallies more power before the clock runs out wins. Read the live board and leaderboard, then enlist (prove you hold the coin) and rally for your side.

Reads are public — point THREE_WS_BASE at a deployment and go. Writes are wallet-scoped: enlisting signs a challenge with your Solana key and the backend confirms a live on-chain holding of the faction coin before issuing a war pass. Factions, members, and momentum come from CoinCommunities + pump.fun; rally power is persisted and ranked server-side. Nothing is mocked.

Install

npm install @three-ws/clash-mcp

Or run with npx (no install):

npx @three-ws/clash-mcp

Quick start

Claude Code, one line:

claude mcp add clash -- npx -y @three-ws/clash-mcp

Claude Desktop / Cursor (claude_desktop_config.json or mcp.json):

{

"mcpServers": { "clash": { "command": "npx", "args": ["-y", "@three-ws/clash-mcp"], "env": { "SOLANA_SECRET_KEY": " " } } } }

Inspect the surface with the MCP Inspector:

npx -y @modelcontextprotocol/inspector npx @three-ws/clash-mcp

Tools

The reads return live data — power and standings move between calls, so neither is idempotent. The writes are wallet-scoped: no funds ever move (a war pass is a signed proof, not a transaction), so neither is destructive. enlist_faction is idempotent (re-enlisting mints an equivalent pass); rally_faction is not (each call appends power).

Input parameters

`get_clash_state` — none.

`get_clash_leaderboard` — faction (optional mint; also returns that faction's top soldiers this round).

`enlist_faction` — token (required faction mint), secret (optional base58 Solana secret; falls back to SOLANA_SECRET_KEY).

`rally_faction` — taps (required, 1–50), and either pass (a war pass from enlist_faction) or token (+ optional secret) to auto-enlist first.

How a battle works

1. Scout. get_clash_state shows the current round: who's matched, each army's power, momentum, and msLeft.
2. Enlist. enlist_faction issues a challenge bound to your wallet + faction, signs it with your Solana key, and the backend verifies the signature and a live on-chain holding of the coin. You get back a warPass. (No holding → eligible:false, reason:"not_a_holder".)
3. Rally. rally_faction spends taps (1–50 per call) from the pass as battle power — multiplied by the faction's live momentum, capped per wallet per round. Call it repeatedly while msLeft > 0.
4. Win. When the round clock hits zero, the army with more power takes the battle and the result is written to each faction's all-time war record (get_clash_leaderboard).

Example

// get_clash_state

{}

{ "ok": true, "epoch": 486231, "epochMs": 3600000, "endsAt": 1750000000000, "msLeft": 1843000, "factionCount": 16, "arena": [ { "id": "486231:…", // each side also carries image, posts, and priceUsd (elided here) "a": { "token": "…", "symbol": "ALPHA", "members": 8200, "momentum": 1.31, "power": 940, "record": { "w": 12, "l": 4, "d": 1, "battles": 17, "power": 8100 } }, "b": { "token": "…", "symbol": "BETA", "members": 5100, "momentum": 1.12, "power": 610, "record": { "w": 7, "l": 9, "d": 0, "battles": 16, "power": 5400 } }, "aShare": 0.61, "leader": "…ALPHA mint…" } ], "bye": null }

// rally_faction — auto-enlist + rally in one call (wallet must hold the coin)

{ "token": "…faction mint…", "taps": 50 }

{ "ok": true, "enlisted": { "wallet": "…", "amount": 1250000, "usd": 84.20 }, "epoch": 486231, "mint": "…faction mint…", "added": 66, "momentum": 1.31, "walletPower": 66, "walletCap": 5000, "capped": false, "factionPower": 1005, "msLeft": 1841000 }

Requirements

• Node.js >= 20.
• Network access to https://three.ws (or your own THREE_WS_BASE).
• For writes only: a base58 Solana secret whose wallet holds the faction coin it enlists for, via SOLANA_SECRET_KEY or the per-call secret arg.

Environment variables

The secret is only ever used to sign the enlist challenge locally — a detached ed25519 signature over the challenge text. It never signs a transaction and no funds move. Still, it controls a wallet: prefer a per-call secret or a dedicated env on a machine you trust.

Errors

A failed tool call returns an MCP error result (isError: true) whose text is a single JSON object: { "ok": false, "error": " ", "message": "…" }, plus status on upstream rejections and detail where the failure carries context (e.g. which wallet was not a holder):
