Cyphrex MCP MCP server

Cyphrex provides a remote MCP server that acts as a security gateway for AI agents. It enforces behavior profiles, blocks unsafe actions before execution, and produces cryptographically signed audit trails anchored on Solana. The server allows agents to register identities, check actions against policies, and scan upstream MCP tools for threats like prompt injection.

Endpoint and access

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http cyphrex-mcp https://mcp.cyphrex.io/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add cyphrex-mcp --url https://mcp.cyphrex.io/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable cyphrex-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "cyphrex-mcp": {
      "url": "https://mcp.cyphrex.io/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "cyphrex-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.cyphrex.io/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start cyphrex-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "cyphrex-mcp": {
      "type": "http",
      "url": "https://mcp.cyphrex.io/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http cyphrex-mcp https://mcp.cyphrex.io/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "cyphrex-mcp": {
      "url": "https://mcp.cyphrex.io/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "cyphrex-mcp": {
      "serverUrl": "https://mcp.cyphrex.io/mcp"
    }
  }
}
