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 🙏

v0.1.5

Published

MCP server for direct blockchain interaction via RPC methods, providing access to on-chain data and state.

Readme

Snak - RPC Plugin

The RPC Plugin provides tools for interacting directly with the Starknet blockchain via RPC (Remote Procedure Call) methods, enabling access to blockchain data and state.

Features

This plugin adds the following RPC tools:

  • get_chain_id: Retrieve the unique identifier (chain ID) of the Starknet network.
  • get_syncing_status: Retrieve the syncing status of the Starknet node.
  • get_class_hash: Retrieve the unique class hash for a contract at a specific address.
  • get_spec_version: Get the current spec version from the Starknet RPC provider.
  • get_block_with_tx_hashes: Retrieve block details including transaction hashes.
  • get_block_with_receipts: Fetch block details with transaction receipts.
  • get_transaction_status: Fetch transaction status by hash.
  • get_block_number: Get the current block number from the Starknet network.
  • get_block_transaction_count: Get the number of transactions in a specific block.
  • get_storage_at: Get the storage value at a specific slot for a contract.
  • get_class: Retrieve the complete class definition of a contract.
  • get_class_at: Fetch the class definition of a contract at a specific address.

Usage

The RPC Plugin is used internally by the Starknet Agent and doesn't need to be called directly. When the agent is initialized, it automatically registers these tools, making them available for use.

Example

When asking the agent to perform RPC-related tasks, it will use the appropriate tool from this plugin:

"What's the current block number?"  // Uses get_block_number
"Show me the status of transaction 0x1234..."  // Uses get_transaction_status
"What's the chain ID of the current network?"  // Uses get_chain_id

Development

To extend this plugin, add new tools in the src/tools directory and register them in the registerTools function in src/tools/index.ts.
