Seraph — Claude Code MCP server for crypto risk checks
Seraph gives AI agents access to crypto transaction risk and firewall tools through a hosted MCP endpoint managed by Kondux. Authentication uses OAuth 2.1.
claude mcp add --transport http seraph https://seraph.kondux.io/mcpWhat Seraph does
Seraph connects AI agents to tools for reviewing crypto transaction risks and applying transaction firewall capabilities. The service runs remotely over Streamable HTTP at https://seraph.kondux.io/mcp and is operated by Kondux.
Before connecting, create a Seraph account or sign in, then finish the setup in its console. Authentication uses OAuth 2.1 through Seraph/Privy, while API-key access remains available to existing integrations. MCP clients that discover OAuth automatically can initiate the sign-in flow from the server endpoint.
The server works with Claude Code, Codex, Cursor, GitHub Copilot, Windsurf (Devin Desktop), Cline, Zed, and Gemini CLI. There is no local package to install; configure the hosted endpoint in your MCP client instead. The public repository contains registry metadata and setup examples, while the production service implementation remains proprietary.
What it helps with
- Connect an AI agent to crypto transaction risk tools
- Route transaction checks through an MCP firewall service
- Configure OAuth access to the hosted Seraph server
- Register Seraph in an MCP client configuration
Example prompts for the agent
- Connect the Seraph MCP server in Claude Code and complete authentication.
- Add Seraph to Codex using
https://seraph.kondux.io/mcpas the remote endpoint. - Prepare a Cursor MCP configuration that connects to Seraph.
