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

@intentface/latch-mcp

The MCP (Model Context Protocol) host for Latch — connect to MCP servers and expose their tools to agents, with per-tenant isolation and brokered auth.

What it does

  • createMcpHost — opens MCP server connections and surfaces their tools as agent tools. SSRF allowlist (allowedHosts) bounds which hosts a connection may reach; the server token/auth is brokered server-side and never reaches the model.
  • createMcpConnections — a ConnectionRegistry over a set of declared MCP connections (static bearer/header token, or interactive oauth). OAuth connections expose a gated connect_<name> tool so an agent can ask the user to authorize mid-chat (and auto-resume).
  • createMcpOAuth — the per-connection OAuth flow (authorize/callback/refresh), Vault-backed per caller. Supports DCR (dynamic client registration) and pre-registered clients (for providers without DCR — Google/GitHub/Slack).
  • createOAuthDiscoveryFetch — normalizes non-conformant discovery docs from proxied servers (force https, strip trailing-slash issuer) so the SDK's strict RFC checks pass.

Usage

import { createMcpConnections } from "@intentface/latch-mcp";

const connections = createMcpConnections<Principal>({
  callbackBaseUrl: `${baseURL}/api/latch/connections`,
  connections: connectionDefs, // { name: { url, auth, normalize? } }
});

Where it fits

A connection source for @intentface/latch-core's registry. The platform also exposes user-added (UI/Vault-stored) MCP connections via the same primitives.
