Sharpclaw, from Imxcstar, is an MCP server tool and autonomous AI agent framework built using C#. It operates on the .NET 10 (or C# 13) runtime, connecting to major LLM providers like Anthropic, OpenAI, and Gemini. Distributed as a NuGet package, it also functions as a terminal-first agent runtime and an embeddable host SDK. Sharpclaw supports agentic CLIs and MCP-enabled workflows, providing essential tools for developers crafting enterprise AI systems and production deployments. Its design emphasizes secure credential management and flexible configuration options.

What does Sharpclaw connect to?

Sharpclaw functions as an autonomous AI agent framework and an MCP server, establishing connections with leading Large Language Model providers. It supports integration with services from Anthropic, OpenAI, and Gemini, enabling a broad range of AI-driven interactions. The framework is designed to interact with various AI clients, including Anthropic's Claude Desktop. Its web server and embedded server endpoints support transport protocols such as SSE and JSON over HTTP, while Stdio is implied for its Terminal UI and CLI.

Core features and tools

Sharpclaw exposes several callable tools for AI agents. These include File System, offering operations like searching, reading, appending, editing, and directory management. Process & Task Management allows executing native OS commands, external processes, HTTP requests, and managing background tasks. For secure code execution, Sandboxed Python runs Python code within a WebAssembly sandbox. Additionally, Sharpclaw enables developers to expose custom .NET methods as MCP endpoints by using specific attributes like "[McpTool]", extending its functional reach.

Who is it for?

Sharpclaw targets teams developing AI developer tools, agentic CLIs, and MCP-enabled workflows. It is also suitable for developers, engineers, and architects focused on enterprise AI systems and production deployments. The platform assists in building C# AI coding assistants and running local or hosted coding-agent CLIs, supporting complex AI initiatives. Skip this if your project does not require integrating with multiple LLM providers or exposing .NET methods as MCP endpoints.

How to get started

The server authenticates using API keys stored securely through cross-platform credential managers. Configuration is managed via standard .NET configuration files and layered SharpClaw JSONC config files, and it supports SSE and JSON over HTTP for transport.

Use cases

• Building C# AI coding assistants.
• Running local or hosted coding-agent CLIs.
• Adding session persistence and auditability to agent workflows.

Sharpclaw provides a foundational framework for developing AI agents and MCP servers, supporting various LLM providers and offering essential tools like File System and Process & Task Management. Its secure authentication and flexible configuration make it suitable for enterprise deployments. Imxcstar designed it for developers building agentic CLIs and AI-powered workflows.
