Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Core logic for MCP JSON tools

Readme

@sylphlab/tools-json

NPM version

Core logic for JSON manipulation and processing.

This package provides the underlying logic and tool definitions for working with JSON data, including parsing, stringifying, and potentially diffing/patching. It's designed using @sylphlab/tools-core and serves as the foundation for @sylphlab/tools-json-mcp.

Purpose

JSON (JavaScript Object Notation) is a ubiquitous data format. This package offers standardized tools for common JSON operations, essential for agents or systems that need to process or transform JSON data. By defining these tools with @sylphlab/tools-core, the logic becomes reusable and adaptable for various platforms like MCP servers.

Tools Provided

  • jsonTool (or similar names for specific operations like parseJson, stringifyJson, diffJson, patchJson): A tool or set of tools to handle:
    • Parsing: Converting a JSON string into a JavaScript object/value.
    • Stringifying: Converting a JavaScript object/value into a JSON string, potentially with formatting options.
    • (Potentially) Diffing: Comparing two JSON objects and generating a description of the differences.
    • (Potentially) Patching: Applying a set of changes (a patch) to a JSON object.

Key Features

  • Standard JSON Operations: Covers parsing and stringifying.
  • Advanced Capabilities (Potential): May include JSON diff and patch functionality.
  • Standardized Definition: Uses the SylphTool structure from @sylphlab/tools-core.
  • Robust Parsing/Stringifying: Leverages standard JavaScript JSON.parse() and JSON.stringify().

Installation

This package is primarily intended for internal use within the mcp monorepo, mainly as a dependency for @sylphlab/tools-json-mcp.

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

Usage (Conceptual)

The tool definitions are typically consumed by adapters or MCP server implementations.

import { jsonTool } from '@sylphlab/tools-json'; // Name might vary
import { adaptToolToMcp } from '@sylphlab/tools-adaptor-mcp'; // Example adapter

// Example: Using the tool definition directly (e.g., parsing)
async function runParseJson() {
  // Input might be structured differently depending on the tool definition
  const input = { jsonString: '{"key": "value", "number": 123}' };
  // Validate input against the specific tool's inputSchema...
  const output = await jsonTool.handler(input); // Or specific parse handler
  // Validate output against the specific tool's outputSchema...
  if (output.success) {
    console.log(output.parsedObject); // Output: { key: 'value', number: 123 }
  } else {
    console.error(output.error);
  }
}

// Example: Adapting for MCP
const mcpJsonTool = adaptToolToMcp(jsonTool); // Adapt the relevant tool(s)

// This adapted definition would then be used to create the MCP server.

Dependencies

  • @sylphlab/tools-core: Provides defineTool and core types.
  • zod: For input/output schema definition and validation.
