Sharp Lens MCP Server

A Model Context Protocol (MCP) server providing 92 AI-optimized tools for .NET/C semantic code analysis, navigation, refactoring, and code generation using Microsoft Roslyn. Its 40 documented tools cover type, code, method, flow. It runs locally over stdio via the published package.

People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in C#.

01 · Install Sharp Lens

before you install - you'll need

Set DOTNET_SOLUTION_PATH before connecting.

Claude Code

claude mcp add pzalutski-pixel-sharplens-mcp -- npx -y sharplens-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "pzalutski-pixel-sharplens-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "sharplens-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package sharplens-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.pzalutski-pixel is GitHub-verified and matches the repo owner

03 · What Sharp Lens can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can find all subclasses, list attributes on a symbol, find types/members by attribute, and map a pasted stack trace to file/line/symbol, mangling undone.

Capability map

Tools grouped from the project's README - what Sharp Lens lets an agent do.

read & search

21 tools - e.g. Semantic info at position; All references; each classified read/write/invocation/cast/typeof/nameof/attribute; optional kind filter; Interface/abstract implementations

get_symbol_info · find_references · find_implementations · find_callers · get_call_graph · find_path_between…

Type

5 tools - e.g. Inheritance chain; All members by type name; Multiple types in one call

get_type_hierarchy · get_type_members · get_type_members_batch · get_external_type_info · check_type_compatibility

Method

3 tools - e.g. Detailed signature by name; All overloads of a method; Navigate to the base member / interface members a member implements

get_method_signature · get_method_overloads · get_super_method

Analyze

3 tools - e.g. Variable assignments and usage; Branching/reachability; What breaks if changed?

06 · Sharp Lens FAQ

Is Sharp Lens still maintained?

Yes - as of 2026-08-25, its last commit was 2026-08-16 and it shipped 4 releases in the last 90 days. We re-verify nightly.

What can Sharp Lens do?

With this server connected, an agent can find all subclasses, list attributes on a symbol, find types/members by attribute, and map a pasted stack trace to file/line/symbol, mangling undone.

How do I install Sharp Lens?

Run `npx -y sharplens-mcp`. The README documents one environment variable (DOTNET_SOLUTION_PATH) to set first. Set DOTNET_SOLUTION_PATH before connecting. You can also paste the ready-made client config above.

Does Sharp Lens run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
