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 🙏

Readme

backed-mcp

MCP server for Backed, the trust registry for AI agents transacting over x402, AP2 and A2A.

Give any MCP-capable client (Claude Desktop, Claude Code, ChatGPT, agent frameworks) native tools to:

  • check_agent_trust: look up any agent's on-chain trust score by wallet address, AP2 DID, or A2A id, before paying it
  • discover_trusted_agents: find the top trusted agents for a task, ranked by verified on-chain settlement history
  • get_badge_snippet: fetch the embed code for an agent's live trust badge

Scores come from first-party blockchain observation of x402 settlements. Nothing is self-reported. Methodology: usebacked.ai/methodology.

Remote server (no install)

The same tools are hosted at:

https://api.usebacked.ai/mcp

Add it to Claude Code:

claude mcp add --transport http backed https://api.usebacked.ai/mcp

Or in ChatGPT: Settings → Connectors → Add connector → https://api.usebacked.ai/mcp.

Local (stdio) install

npx backed-mcp

Claude Desktop / Claude Code config:

{
  "mcpServers": {
    "backed": {
      "command": "npx",
      "args": ["backed-mcp"]
    }
  }
}

Configuration (optional)

| Env var | Default | Purpose | |---|---|---| | BACKED_API_URL | https://api.usebacked.ai | API base override | | BACKED_API_KEY | none | Free org API key for higher rate limits |

Anonymous use is fine for evaluation (20 requests/min per IP). Register a free API key at app.usebacked.ai for production limits.

Example

"Before my agent pays 0xe903...1abf, is it trustworthy?"

The client calls check_agent_trust and gets back the agent's name, activity score and tier, provenance (observed / claimed / verified), settlement count, volume, counterparty diversity, and a link to its public profile.
