# three.ws Alerts

An MCP server that lets your agent define pump.fun alert rules and read back what fired, across three delivery channels.

## What it does

Your agent gets five tools: list, create, update and delete rules, plus alert history. Rules watch pump.fun events such as token graduations, market-cap thresholds, large buys and new mints. Evaluation runs on the three.ws cron, so a rule fires with no dashboard open.

Delivery goes in-app, to an HTTPS webhook, or to Telegram. Each rule with a webhook gets its own secret, used to sign a request header so you can verify the call on your end. Repeated fires are throttled by `cooldown_seconds`.

Node.js 20 or newer is required, along with the `__Host-sid` cookie from a signed-in three.ws session, passed as `THREE_WS_SESSION`. That value grants account access — store it like a password. Without a live session the server has nothing to write to, since every call is account-scoped. `create_alert_rule` adds a new rule on each call, so a retry after a timeout can hit the rule cap; pause with `update_alert_rule` and `enabled:false` instead of using delete, which wipes the history too.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `THREE_WS_BASE`, `THREE_WS_TIMEOUT_MS`, `THREE_WS_SESSION` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- watch token graduations and get a Telegram message
- catch large SOL buys on a specific mint
- review fired alerts with per-channel delivery health
- pause a rule without losing its delivery history
- spot a market anomaly by processor and severity level

## Example prompts
- List my alert rules and their delivery health
- Create a graduation rule for agent `8a1c…-uuid` with a webhook and Telegram
- Show the last two alerts that fired
