prysmatic-mcp 0.1.1

Query the Prysmatic API (tracked wallets and tokens) from Claude and other MCP clients.

Prysmatic MCP

Lets Claude (or any MCP client) query the Prysmatic API with your API key. It adds five tools for looking up tracked wallets and tokens. Each call uses your credits, just like the REST API.

Tools

Tool	What it returns
list_wallets(page=1)	Tracked wallets, 25 per page
wallet_metrics(alias)	Metrics for one wallet
wallet_holdings(alias)	Tokens a wallet currently holds
tokens_held(min_wallets=2, page=1)	Tokens held by several wallets
token_swaps(mint, aggregate=False, tracked_only=True)	Wallet swaps on a token

Requirements

• Python 3.10+
• A Prysmatic API key with credits (from the dashboard).

Add to Claude

Easiest (no install, needs uv):

claude mcp add prysmatic -e PRYSMATIC_API_KEY=<your_key> -- uvx prysmatic-mcp

Or install it first:

pipx install prysmatic-mcp
claude mcp add prysmatic -e PRYSMATIC_API_KEY=<your_key> -- prysmatic-mcp

Configuration

Env var	Required	Default
PRYSMATIC_API_KEY	yes	—
PRYSMATIC_API_BASE	no	https://api.prysmatic-sol.xyz

Errors

Tools return a readable message instead of crashing: bad/missing key (401), out of credits (402), or not found (404).
