sigsci-mcp-server

MCP server implementation for the Signal Sciences (Fastly NGWAF) API.

日本語版はこちら → README.ja.md

Implements the Code execution with MCP approach to minimize context consumption from tool definitions.

Features

  • Progressive Disclosure: Dynamically discover and load only the tools you need

  • 40+ API tools: Read-only corp/site APIs supported

  • Type-safe: Fully typed with TypeScript

  • MCP compliant: Built on the Model Context Protocol SDK

Related MCP server: appd-mcp

Usage

Configure for Cursor / Claude Desktop

  • Add to ~/.cursor/mcp.json or claude_desktop_config.json:

{
  "mcpServers": {
    "sigsci-mcp-server": {
      "command": "npx",
      "args": ["-y", "https://github.com/yuki777/sigsci-mcp-server"],
      "env": {
        "SIGSCI_EMAIL": "your-email@example.com",
        "SIGSCI_TOKEN": "your-api-token"
      }
    }
  }
}

Using Progressive Disclosure

This MCP server implements Anthropic’s recommended Code execution with MCP approach.

Problems with traditional MCP

  1. Tool definitions consume context: Preloading all definitions costs many tokens

  2. Redundant intermediate results: API responses can flood context as-is

How this server addresses them

  1. On-demand tool discovery: Use sigsci_search_tools and sigsci_list_tool_categories to find only what you need

  2. Control detail level: detailLevel lets you choose name-only/with descriptions/full definitions

  3. Tool definitions as resources: Access tool definition files as MCP resources

Example

// 1. Check categories first
await sigsci_list_tool_categories({ detailLevel: "name" });

// 2. Search for the needed tools
await sigsci_search_tools({ keyword: "request", detailLevel: "description" });

// 3. Call only the needed tools
await sigsci_search_requests({
  corpName: "my-corp",
  siteName: "my-site",
  q: "tag:XSS",
});
