Run this in a terminal to add the server to Claude Code.
What this does
SRA-RiskGate exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.
Requirements
This server needs the following environment variables to be set before it can run:
SRA_BASE_URL SRA_MODEL SRA_MAX_AMOUNT SRA_KNOWN_RECIPIENTS SRA_KNOWN_RECIPIENTS_FILE SRA_BLOCKED_ADDRESSES SRA_BLOCKED_ADDRESSES_FILE SRA_MAX_AUTH_VALIDITY_SECONDS SRA_API_KEY SRA_TIMEOUT SRA_DEPEG_HOLD_PCT SRA_DEPEG_REJECT_PCT SRA_MAX_GATEWAY_VALIDITY_SECONDS SRA_CIRCLE_WALLETS SRA_CIRCLE_USDC_TOKEN_IDS SRA_EXPECTED_DELEGATES SRA_EXPECTED_DELEGATES_FILE
Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
Frequently asked questions
