How to Set Up and Use Ultrasharp Tools
Ultrasharp Tools is a .NET-powered MCP server designed specifically for C# codebases, using the Roslyn compiler API to give AI agents semantic understanding of your code rather than treating it as plain text. It parses entire solutions into an in-memory structural model—handling 500K lines in ~10 seconds and serving repeated lookups from cache in 20ms—enabling precise search, targeted edits, automatic linting and formatting, static debugging, and backwards crash analysis. Teams working on large C# solutions can connect Claude or other AI agents through this server to perform intelligent refactoring, dependency impact analysis, and automated git commits without wasting tokens on full-file reads.
Prerequisites
- .NET 10 runtime installed on the machine running the server
- A C# solution (.sln) or project (.csproj) on the local filesystem
- Roslyn-compatible project structure (standard .NET SDK projects)
- An MCP-compatible client such as Claude Code or Claude Desktop
- Optional: Ollama or Text Embeddings Inference (TEI) for semantic vector search features
Download the release binary
Download the latest release archive for your platform from the GitHub Releases page and extract it to a directory such as /path/to/ultrasharp-tools.
# Visit https://github.com/faxenoff/ultrasharp-tools-mcp/releases
# Download and extract the archive for your OSConfigure your MCP client
Add the server to your Claude configuration. On macOS/Linux use the ultrasharp-tools wrapper script; on Windows use UltraSharp-tools.com. The first Comm process automatically launches the Droid daemon.
Optional: set up semantic embedding
Run the setup wizard script to configure vector search via Ollama or TEI in Docker. This enables semantic_replace and context-aware queries across large codebases.
# macOS/Linux
/path/to/ultrasharp-tools/Scripts/setup-semantic-embedding.sh
# Windows
C:\Tools\UltrasharpTools\Scripts\setup-semantic-embedding.cmdOpen your C# solution in the AI agent
Point the agent at your .sln file. The server will parse the solution and build its structural cache. Subsequent access hits the in-memory cache at near-zero latency.
Use natural language to work with the codebase
Ask the AI agent to find usages, add methods, rename symbols, or show impact analysis. All changes are linted and formatted automatically after each modification.
Ultrasharp Tools Examples
Client configuration
Add ultrasharp-tools to your .claude.json or claude_desktop_config.json pointing to the extracted binary.

}Prompts to try
Example prompts that leverage Roslyn-based semantic analysis through the MCP server.
- "Add a ValidateEmail method to the UserService class"
- "Show all places where PaymentProcessor is used across the solution"
- "Rename GetUser to FetchUserAsync and update all call sites"
- "What will break if I change the IAuthService interface?"
- "Find duplicate implementations of this logging method in the project"Troubleshooting Ultrasharp Tools
The server fails to start on macOS with an ENOEXEC error
Use the ultrasharp-tools wrapper script rather than invoking the .com binary directly. Alternatively, upgrade zsh to 5.9+ via 'brew install zsh' which allows .com binaries to execute natively.
Solution parsing is slow or the cache is not being used
The first parse of a large solution takes 10-50 seconds depending on size. Subsequent requests use the in-memory cache. Ensure the Droid daemon process is running (check with ps for a process named Droid). If it crashed, restart the Comm process to re-launch it.
Semantic search returns no results even though the code exists
Semantic vector search requires Ollama or TEI to be running with an embedding model configured. Run the setup-semantic-embedding script and confirm the embedding service is reachable before retrying semantic queries.
