# MemePump — Solana token safety checker, REST API and read-only MCP server for AI assistants

> MemePump (the site also appears as MemeAI) checks Solana tokens for rug-pull and honeypot signals: risk score, honeypot signal, liquidity lock, mint and freeze authority, holder concentration and wallet clusters. Use it from the free web checker, a Telegram bot, a REST API or an MCP server. It is read-only: it cannot trade, sign or move funds and never asks for a wallet key. Output is informational, not financial advice.

Official MCP Registry name `org.memepump/memepump`.

## Agent quickstart (summary; full version: https://memepump.org/mcp.md)

1. Discover: this file, the server card, or the registry name above.
2. Connect: `https://memepump.org/api/mcp` (Streamable HTTP, POST only, stateless). No sign-in is needed. An optional MemePump API key as `Authorization: Bearer msk_live_...` raises the rate limits and applies the key's monthly quota. There is no OAuth.
3. Call: `check_token_safety` with `mint` (a base58 Solana token address) → optionally `get_token_holders` with `mint` and `limit` (1 to 25) → `explain_risk_signals` to define a field in plain words.
4. Handle errors: HTTP 429 (wait `Retry-After` seconds, retry once); HTTP 401 (the Bearer key is wrong or inactive; stop and tell the human); a tool result with `isError` (invalid mint, data temporarily unavailable, or the key's monthly calls used up; do not invent a verdict).
5. Hand off: give the human the verdict with its source (RugCheck analysis of on-chain data), say it is informational and not financial advice, and link `report_url`.

## Human oversight (what exists today)

- Nothing to approve: every tool is read-only; the server has no trading, signing or transfer tools and never asks for a wallet or private key.
- With an API key: the dashboard https://memepump.org/dashboard shows plan and calls used; `GET /api/v1/account/usage` returns calls used and remaining; rotating the key in the dashboard stops the old key at once.
- Without a key there is nothing to revoke; remove the connector in the AI client to stop it.
- Whether the client asks before each tool call is the client's setting, not enforced by MemePump.

## What it does

- **Token safety report** (`check_token_safety`): risk score 0 to 100 (0 is lowest risk) with a level (Good, Unknown, Risky, Dangerous, Scam), honeypot signal, liquidity-lock status, mint and freeze authority, top-holder concentration, total liquidity and warnings. Data is RugCheck analysis of Solana on-chain data, cached up to 4 hours.
- **Holders and clusters** (`get_token_holders`): top holders with share of supply, holder type and risk flags, plus wallet clusters that share a funder or move tokens between each other.
- **Signal definitions** (`explain_risk_signals`): what each field means and what it cannot show.
- **Free web checker**: https://memepump.org/token-check (no login; limited per IP). Free tools: https://memepump.org/tools/solana-token-holders and https://memepump.org/tools/solana-wallet-checker.
- **REST API**: `GET /api/v1/token/:mint/safety` with `X-API-Key`; docs and pricing at https://memepump.org/api-docs.
- **Answers**: https://memepump.org/answers has short answers on rug pulls, honeypots, authorities, liquidity locks and holder concentration (each has a `.md` twin).

## Pricing

## Limits worth knowing

- Solana only. Data can be delayed, incomplete or wrong; a low risk score is not a guarantee a token is safe.
- Not financial, investment or legal advice.
