snap-crewai-tools

CrewAI tools for SNAP — private agent-to-agent payments on Solana using zero-knowledge proofs.

Install

pip install snap-crewai-tools
# for the deposit/withdraw flow via the SNAP MCP server:
pip install "snap-crewai-tools[mcp]"   # also requires Node.js (npx)

Native tools (pure Python)

snap_list_pools and snap_estimate_fee work with no JS dependency:

from crewai import Agent
from snap_crewai_tools import create_snap_tools

tools = create_snap_tools()  # [SNAPListPoolsTool, SNAPEstimateFeeTool]

agent = Agent(
    role="Payments analyst",
    goal="Inspect SNAP pools and fees",
    tools=tools,
)

Full flow: deposit & withdraw via the SNAP MCP server

Deposit and withdraw require Groth16 proof generation (in the TypeScript SDK), so in Python those run through the published snap-mcp-server using CrewAI's MCPServerAdapter:

from crewai import Agent
from crewai_tools import MCPServerAdapter
from snap_crewai_tools.mcp import snap_mcp_server_params

params = snap_mcp_server_params(
    rpc_url="https://your-rpc-url.com",
    pool_address="B8SyffZKt8LABKogWjH9rZcjY5PV2hyYRCbTxxbcrpFf",
)

with MCPServerAdapter(params) as tools:
    # tools includes snap_deposit, snap_withdraw, snap_withdraw_private,
    # snap_estimate_fee, snap_list_pools, snap_pool_info, snap_balance
    agent = Agent(role="Treasurer", goal="Pay agents privately", tools=tools)
