ReSharper Inspections

Two tools run JetBrains ReSharper code inspections over your .NET code and return structured findings — hundreds of inspections beyond what the C# compiler / Roslyn report. They complement (do not replace) the code analysis tools.

Tool	Scope
resharper_inspect_solution	A whole solution (.sln)
resharper_inspect_project	A single project (.csproj)

Self-installing engine

On the first inspection, debug-mcp downloads and caches the ReSharper command-line engine (JetBrains.ReSharper.GlobalTools, a ~180 MB one-time acquisition) into ~/.debug-mcp/resharper/<version>/. No manual installation is required. Every later inspection reuses the cached, version-pinned engine. The download happens lazily on first use — never at server startup — and requires network access and a .NET SDK on the host.

Opt-out

The integration is on by default, exactly like the Roslyn code_* tools. Disable it (and skip the engine download entirely) with:

debug-mcp --no-resharper

When disabled, the resharper_* tools are not advertised and every other tool keeps working. Related flags: --resharper-cache <dir>, --resharper-version <ver> (and env vars DEBUG_MCP_NO_RESHARPER, DEBUG_MCP_RESHARPER_CACHE, DEBUG_MCP_RESHARPER_VERSION).

Parameters

Param	Tools	Description
solutionPath / projectPath	resp.	Absolute path to the .sln / .csproj.
severity	both	Minimum native severity: error | warning | suggestion | hint.
project	solution	Restrict a solution inspection to one project.
noBuild	both	Skip the engine's pre-analysis build when already built.
timeoutSeconds	both	Per-call inspection budget (10–1800s); excludes the one-time engine download (separate budget).
maxResults	both	Cap on returned findings (default/max 500).

Native severities

Findings report ReSharper's native severity verbatim — error, warning, suggestion, hint. These are kept distinct (a ReSharper suggestion and hint are not merged), so the threshold filter and summary counts reflect ReSharper's own classification rather than Roslyn's coarser scale.

Example response

}

Errors

Structured { "success": false, "error": { "code", "message", "details" } } with codes: INVALID_PATH, INVALID_PARAMETER, PROJECT_NOT_FOUND, PREREQUISITE_MISSING (no .NET SDK), ENGINE_ACQUISITION_FAILED (offline / install failure), BUILD_FAILED, INSPECTION_FAILED, and TIMEOUT (with details.phase = acquisition or inspection). A failure here never crashes the server or affects other tools.
