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 my mcp-ts-template, a foundation for creating robust, modern MCP servers in TypeScript. The template provides a rich feature set including DI, pluggable auth, abstracted storage, and first-class support for serverless runtimes like Cloudflare Workers.

Core Infrastructure & Tooling

Project Features
TypeScript mcp-ts-template
  • A template for building MCP servers in TypeScript.
  • Includes declarative tools, elicitation, auth, storage, and OpenTelemetry.
TypeScript model-context-protocol-resources
  • A collection of guides and utilities for the Model Context Protocol (MCP).
  • Includes several example server implementations to showcase different capabilities.
TypeScript workflows-mcp-server
  • Provides structure to AI agents to execute complex, multi-step workflows from YAML files.
  • Simplifies automation and task organization for LLMs.
TypeScript mcp-reporter
  • A utility that generates comprehensive human-friendly capability reports for MCP servers.
  • Helps developers understand available functionality.

Data & Research Platforms

Project Features
TypeScript atlas-mcp-server
  • Neo4j-powered task management system for LLM Agents.
  • Features a three-tier architecture (Projects, Tasks, Knowledge) and Deep Research capabilities.
TypeScript protein-mcp-server
  • Provides programmatic access to 3D protein structural data from RCSB PDB, PDBe, and UniProt.
  • Features tools for search, retrieval, and analysis.
TypeScript clinicaltrialsgov-mcp-server
  • Tools to search, retrieve, compare, and analyze clinical trials from ClinicalTrials.gov.
  • Includes patient eligibility matching and trend analysis.
TypeScript pubmed-mcp-server
  • Equips AI agents with tools to search, analyze, and retrieve biomedical literature from PubMed.
  • Includes a research agent scaffold for advanced workflows.
TypeScript pubchem-mcp-server
  • Offers a suite of LLM tools for the PubChem PUG REST API, providing access to chemical compounds and bioassays.
TypeScript survey-mcp-server
  • Transform LLMs into intelligent interviewers.
  • Enables LLMs to conduct dynamic, conversational surveys with conditional logic and structured data collection.

Development & System Utilities

Project Features
TypeScript git-mcp-server
  • Provides version control capabilities for LLM agents, supporting a wide range of Git operations.
TypeScript filesystem-mcp-server
  • Tools for file and directory management, including search/replace and directory traversal.
TypeScript obsidian-mcp-server
  • Enables AI agents to interact with an Obsidian vault via the Local REST API plugin for note and knowledge management.
TypeScript toolkit-mcp-server
  • Provides a suite of system utilities for LLM agents, including tools for network diagnostics and system monitoring.
TypeScript ntfy-mcp-server
  • Integrates with the ntfy push notification service, allowing AI agents to send customizable notifications to external devices.

AI & External Service Integrations

Project Features
TypeScript perplexity-mcp-server
  • Unlocks Perplexity's search-augmented AI capabilities for LLM agents, with robust error handling and citation support.
TypeScript mentor-mcp-server
  • Offers AI-powered mentorship for LLM agents via the Deepseek API, providing a 'second opinion' for code reviews and design critiques.
TypeScript github-mcp-server

💡 Other Projects

Project Features
Python repo-map
  • Generates AI-powered visual summaries of codebases.
  • Features efficient caching, multi-language support, and respects gitignore rules.
  • Aids in understanding and documenting projects.
JavaScript claude-sidebar-modifier
  • Firefox browser extension
  • Disables or adjusts the sidebar width on Claude.ai
  • Offers a customized interface
TypeScript scripts-ts
  • Cross-platform, standalone TypeScript utility scripts
  • Automates common development tasks
  • Manages artifacts, structures, and dependencies

💼 Open to Opportunities

I'm seeking full-time and contract roles in AI/LLM-native development and infrastructure. With experience in building autonomous agents and custom MCP servers, I'm ready to tackle new challenges.

Available for:

  • Full-time Positions
  • Contract & Consulting Engagements
  • Custom MCP Server Development (view template)

☕ 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.
