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

agent-tools-runtime-pi-extension

A Pi package that connects agent-tools-runtime to Pi natively, without going through MCP at all.

Why this exists, not pi-mcp-adapter

Pi has no built-in MCP support -- the community bridge is pi-mcp-adapter, which exposes MCP servers through a single proxy tool. Tested live against this runtime: it never worked in headless (-p) mode. The root cause is documented in Pi's own security.md: activating an MCP server goes through /mcp or /mcp setup, both explicitly described as "interactive panel and first-run onboarding surface" -- there is no CLI equivalent for automation.

Pi extensions sidestep that entirely: pi.registerTool() runs when the extension loads, before any interactive gate. This package does tools/list against agent-tools-runtime's Streamable HTTP transport at startup and registers each real facade tool as a native Pi tool -- reusing the three fixed argument shapes runtime/mcp-server.mjs already defines (discover/call/run_skill), hand-mirrored in typebox instead of forwarding raw JSON Schema.

Verified live end-to-end (see the root README's client-comparison section): correctly discovered and called real plugin skills/tools, found the same real data eve (a client with native MCP support) found for the same task.

Install

pi install npm:agent-tools-runtime-pi-extension

Or try it once without installing:

pi -e npm:agent-tools-runtime-pi-extension

Configure

agent-tools-runtime must be running with its Streamable HTTP transport:

npm run mcp:http   # inside the agent-tools-runtime repo, default port 8321
export AGENT_TOOLS_HTTP_URL="http://127.0.0.1:8321/mcp"   # default if omitted

What it registers

Every facade tool agent-tools-runtime currently exposes -- agent_tools_help, agent_tools_exec, and agent_tools_<plugin>_discover / _call / _run_skill for each loaded plugin -- fetched live at extension load time, so the tool list always matches whatever plugins the runtime has loaded. No manual sync required when a plugin is added or removed on the runtime side.
