Software engineer in Seattle. I build open source tools, mostly around the Model Context Protocol (MCP) — giving LLMs structured ways to use external services, data sources, and system APIs.
All of these are built on my mcp-ts-template, a TypeScript starter for MCP servers with DI, pluggable auth, abstracted storage, and Cloudflare Workers support.
| Project | Description |
|---|---|
 mcp-ts-template |
Template for building MCP servers in TypeScript. Declarative tools, elicitation, auth, storage, and OpenTelemetry. |
| model-context-protocol-resources |
Guides, utilities, and example server implementations for MCP. |
| workflows-mcp-server |
Runs multi-step workflows defined in YAML files. Gives agents a structured way to execute complex task sequences. |
| mcp-reporter |
Generates human-readable capability reports for MCP servers — what tools are available, what they do, how to call them. |
| Project | Description |
|---|---|
| atlas-mcp-server |
Neo4j-backed task management for LLM agents. Three-tier model: projects, tasks, and knowledge nodes. Includes deep research capabilities. |
| protein-mcp-server |
Access to 3D protein structure data from RCSB PDB, PDBe, and UniProt. Search, retrieve, and analyze structural records. |
| clinicaltrialsgov-mcp-server |
Search and analyze clinical trials from ClinicalTrials.gov. Includes patient eligibility matching and trend analysis. Try it live. |
| pubmed-mcp-server |
Search and retrieve biomedical literature from PubMed. Includes a research agent scaffold for multi-step literature workflows. |
| pubchem-mcp-server |
LLM tools for the PubChem PUG REST API — chemical compound lookups, bioassay data, and substance search. |
| survey-mcp-server |
Lets LLMs conduct conversational surveys with conditional logic and structured data collection. |
| Project | Description |
|---|---|
| git-mcp-server |
Git operations for LLM agents — commits, branches, diffs, logs, and more. |
| filesystem-mcp-server |
File and directory management: read, write, search/replace, and directory traversal. |
| obsidian-mcp-server |
Interact with an Obsidian vault via the Local REST API plugin. Read, write, and search notes. |
| toolkit-mcp-server |
System utilities for LLM agents: network diagnostics, system info, and monitoring. |
| ntfy-mcp-server |
Send push notifications via ntfy from an LLM agent. |
| pixoo-mcp-server |
Push pixel art, animations, and text to Divoom Pixoo LED matrices. Supports layered scenes, multi-frame animation, and device control. |
| Project | Description |
|---|---|
| perplexity-mcp-server |
Search-augmented AI via the Perplexity API, with citation support. |
| mentor-mcp-server |
Second-opinion code reviews and design critiques via the Deepseek API. |
| github-mcp-server |
[DEPRECATED] — Use the official GitHub MCP Server. |
| Project | Description |
|---|---|
| pixoo-toolkit |
TypeScript toolkit for Divoom Pixoo displays (16, 32, 64). Pixel rendering, animations, and device control over local HTTP. |
 repo-map |
Generates visual summaries of codebases using AI. Caches results, supports multiple languages, respects gitignore. |
 claude-sidebar-modifier |
Firefox extension that disables or resizes the Claude.ai sidebar. |
| scripts-ts |
Cross-platform TypeScript utility scripts for common dev tasks. |
 TwilightAscensionRares |
WoW addon for tracking Twilight Highlands rare spawns (Two Minutes to Midnight achievement). Live schedule, countdown timers, waypoints, and raid/chat sharing. |
I'm looking for full-time and contract roles in AI/LLM tooling and infrastructure. I've spent the last year building autonomous agents and MCP servers, and I want to keep going.
Available for:
- Full-time positions
- Contract and consulting
- Custom MCP server development (view template)
If any of this has been useful to you, I'd appreciate the support.
