@sylphlab/tools-adaptor-mcp

Bridge the gap between SylphLab Tools and the Model Context Protocol (MCP)!

This package provides essential adapter functions to seamlessly convert tool definitions created using @sylphlab/tools-core into the format required by the @modelcontextprotocol/sdk. It's a crucial internal component for building MCP-compliant tool servers within the SylphLab ecosystem.

Purpose

When building tools using the @sylphlab/tools-core defineTool function, you get a standardized tool definition object. However, to expose these tools via an MCP server, they need to conform to the schema expected by the MCP SDK.

@sylphlab/tools-adaptor-mcp handles this conversion, translating the input/output schemas (often defined using Zod) and other metadata into the structure the MCP server understands.

Key Features

• Automatic Conversion: Takes a SylphTool definition and outputs an MCP-compatible tool definition.
• Schema Translation: Handles the conversion of Zod schemas (used in @sylphlab/tools-core) into JSON Schema format suitable for MCP.
• Metadata Mapping: Correctly maps tool names, descriptions, and parameters.
• Simplifies MCP Server Creation: Abstracts away the complexities of manual tool definition conversion, allowing developers to focus on the tool's core logic.

Installation

This package is primarily intended for internal use within the mcp monorepo. If you are developing a new MCP tool server package within this repository, you can add it as a dependency:

# From the root of the monorepo
pnpm add @sylphlab/tools-adaptor-mcp --filter <your-new-mcp-package-name>

Usage (Conceptual)

Typically, you would use this adapter within the main file of an MCP server package (e.g., packages/tools-filesystem-mcp/src/index.ts):

import { createMcpServer } from '@modelcontextprotocol/sdk/server';
import { adaptToolToMcp } from '@sylphlab/tools-adaptor-mcp';
import { filesystemTools } from '@sylphlab/tools-filesystem'; // Assuming this exports an array of SylphTool definitions

// Adapt each SylphTool definition to the MCP format
const mcpTools = filesystemTools.map(adaptToolToMcp);

// Create the MCP server instance
const server = createMcpServer({
  name: 'sylphlab-filesystem',
  description: 'Provides filesystem tools via MCP',
  tools: mcpTools,
  // ... other server options
});

// Start the server
server.start();

(Note: The actual implementation might vary based on the specific server setup.)

Dependencies

• @modelcontextprotocol/sdk: The core SDK for building MCP servers and clients.
• @sylphlab/tools-core: Provides the base SylphTool definition format.
• zod: Used for schema definition and validation.
