Hi, I'm Casey 👋

Software Engineer based in Seattle. Passionate about sharing knowledge through open source.

I'm currently working on projects related to the Model Context Protocol (MCP), trying to build a better way for LLMs to interact with the world. I believe AI is an incredibly powerful tool and I'm hoping to make it more accessible and useful for everyone.

🚀 What I'm Building with MCP

All projects are built on top of my mcp-ts-template, which provides a comprehensive foundation for quickly building high-quality, production-ready MCP servers in TypeScript.

Project	Features
model-context-protocol-resources	A rich collection of guides and utilities for the Model Context Protocol (MCP). Includes several example server implementations to showcase different capabilities.
mcp-ts-template	Production-ready TypeScript template for building robust MCP servers. Features built-in logging, error handling, and security. Built with type safety, extensibility, and testing in mind.
atlas-mcp-server	Neo4j-powered task management system for LLM Agents. Features a three-tier architecture (Projects, Tasks, Knowledge) and Deep Research capabilities.
clinicaltrialsgov-mcp-server	Provides LLM tools to access the ClinicalTrials.gov REST API. Enables searching, retrieving, and analyzing clinical trial data.
filesystem-mcp-server	Offers platform-agnostic tools for file and directory management. Includes advanced features like search/replace and directory tree traversal.
obsidian-mcp-server	Enables AI agents to interact with an Obsidian vault via the Local REST API plugin. Provides tools for managing notes, tags, and frontmatter.
mentor-mcp-server	Offers AI-powered mentorship for LLM agents via the Deepseek API. Provides a 'second opinion' for code reviews, design critiques, and brainstorming.
toolkit-mcp-server	Provides a suite of system utilities for LLM agents. Includes tools for network diagnostics, system monitoring, and cryptographic operations.
github-mcp-server	[DEPRECATED] - Use the official GitHub MCP Server Manage repositories, issues, and pull requests Structured interface for LLM agents
git-mcp-server	Provides comprehensive version control capabilities for LLM agents. Supports a wide range of Git operations, including clone, commit, branch, and merge.
ntfy-mcp-server	Integrates with the ntfy push notification service. Allows AI agents to send highly customizable notifications to external devices.
perplexity-mcp-server	Unlocks Perplexity's search-augmented AI capabilities (Search & Deep Research) for LLM agents. Features robust error handling and secure input validation. Displays citations in a user-friendly format.
pubmed-mcp-server	Equips AI agents with tools to search, retrieve, and analyze biomedical literature from PubMed. Includes a research agent scaffold for advanced workflows.
pubchem-mcp-server	Offers a suite of LLM tools for the PubChem PUG REST API. Provides programmatic access to chemical compounds and bioassays.
mcp-reporter	A utility that generates comprehensive human-friendly capability reports for MCP servers. Helps developers understand available functionality across their MCP ecosystem.
workflows-mcp-server	Provides structure to AI agents to execute complex, multi-step workflows from YAML files. Simplifies automation and task organization for LLMs.

💡 Other Projects

Project	Features
repo-map	Generates LLM-enhanced summaries of repositories Provides insights into project structure and file purposes Supports various programming languages
claude-sidebar-modifier	Firefox browser extension Disables or adjusts the sidebar width on Claude.ai Offers a customized interface
scripts-ts	Cross-platform, standalone TypeScript utility scripts Automates common development tasks Manages artifacts, structures, and dependencies

💼 Looking for Opportunities

I'm actively looking for software engineering roles in AI/LLM development and infrastructure, with experience in building LLM agents, MCP servers & clients, and general AI tools.

Available for:

• Full-time software engineering positions
• Contract work and consulting
• Custom MCP server development using my TypeScript template

Feel free to reach out - I'm always looking for ways to improve my skills and help others do the same.

☕ Support My Work

If my open source work has benefited you, consider sending me some support if you can. I'm a solo developer and your support helps me continue to create and maintain these projects.
