MCP server
The Prysmatic MCP server lets an AI agent (Claude Code, Claude Desktop, or any MCP client) query the Prysmatic API as built-in tools. It is a thin client over the REST API: every call uses your API key and spends credits, exactly like a direct REST call.
Tools
| Tool | Maps to |
|---|---|
list_wallets(page=1) | List tracked wallets |
wallet_metrics(alias) | Wallet metrics |
wallet_holdings(alias) | Wallet holdings |
tokens_held(min_wallets=2, page=1) | Tokens held by multiple wallets |
token_swaps(mint, aggregate=False, tracked_only=True) | Token swaps |
Requirements
- An MCP client (for example, Claude Code).
- Python 3.10 or newer.
- A Prysmatic API key with credits.
Install as a plugin (tools + skill)
The fastest path bundles the MCP tools and a usage skill as a Claude Code plugin. Set your key in the environment first, then add the marketplace and install:
export PRYSMATIC_API_KEY=your_key
/plugin marketplace add eserya77/prysmatic-mcp
/plugin install prysmatic@prysmatic-mcp
This path uses uv: the plugin launches the server with uvx.
Install the MCP only
pipx install prysmatic-mcp
claude mcp add prysmatic prysmatic-mcp -e PRYSMATIC_API_KEY=your_key
Verify with claude mcp list; the server should report Connected.
Configuration
| Variable | Required | Default |
|---|---|---|
PRYSMATIC_API_KEY | yes | none |
PRYSMATIC_API_BASE | no | https://api.prysmatic-sol.xyz |
