prysmatic-mcp 0.1.2

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

Prysmatic MCP

Five MCP tools to query the Prysmatic API (tracked wallets and tokens) from Claude or any MCP client. Each call uses your API key and spends credits, like the REST API.

Requirements

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

Tools

Tool	Returns
list_wallets(page=1)	Tracked wallets, 25/page
wallet_metrics(alias)	Metrics for one wallet
wallet_holdings(alias)	Tokens a wallet 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

Install

Use pipx (isolated venv, puts the command on PATH, won't break other deps):

pipx install prysmatic-mcp

No pipx yet? pip install pipx && pipx ensurepath, then reopen the terminal.

Add to Claude

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

Notes:

• The -e flag must come last (it's variadic; before the command it swallows it).
• Verify with claude mcp list → prysmatic ✔ Connected.

Windows without pipx

pip install prysmatic-mcp installs prysmatic-mcp.exe into the user Scripts dir, which is often not on PATH (connect fails). Either use pipx, or pass the full path:

claude mcp add prysmatic "%APPDATA%\Python\Python313\Scripts\prysmatic-mcp.exe" -e PRYSMATIC_API_KEY=<your_key>

(adjust the Python version in the path).

Configuration

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

Update

pipx upgrade prysmatic-mcp

Errors

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