Overview

Three production MCP servers demonstrating full-spectrum protocol expertise — from local stdio transport for AI coding agents, to remote OAuth-secured enterprise workflow integration, to QA automation with subagent spawning. Full feature set coverage across tools, resources, prompts, sampling, and multiple auth patterns.

Key Features

What Was Built

01

SVG Development Server

instructions, resources, guides, tools for AI coding agents working with SVG assets natively. Collaborated with design team. Open sourcing soon.

02

Flume AI Internal Server

integrates ConstructionWire, Apollo, HubSpot into unified workflow tooling for AI chat agents. Full feature set: OAuth, stdio, tools, resources, prompts, sampling.

03

Fraq QA/Dev Server

integrated into dev and QA workflows. Spawns subagents that log in as users, perform operations, validate pre/post execution results.

Architecture

How It's Built

01

stdio transport (local) — TypeScript, for AI coding agent tooling

02

HTTP + SSE transport (remote) — Python, OAuth 2.0 secured

03

Streamable HTTP — TypeScript, remote subagent spawning

04

Multi-tool orchestration and dynamic tool registration

05

Resource subscriptions and context injection patterns

06

Agent-to-agent communication via subagent spawning
