Run Conformance From Branch

Run Conformance From Branch

Run C# SDK conformance tests against an unpublished modelcontextprotocol/conformance branch (including branches in forks).

Use Cases

• Validate a conformance PR before it is published to npm
• Validate C# SDK behavior against a fork with custom scenario changes
• Reproduce failures caused by conformance changes

Safety / Repo Hygiene

1. Start from a clean git state.
2. Commit or stash local changes first.
3. Restore pinned dependencies when done (npm ci).

Inputs

• Source type: upstream-branch or fork-branch
• Source locator:
  • Upstream branch: modelcontextprotocol/conformance#<branch>
  • Fork branch: <owner>/conformance#<branch>
• Scenario (optional): e.g. auth/scope-step-up

Workflows

A) Install directly from GitHub branch (upstream or fork)

From csharp-sdk root:

npm install --no-save @modelcontextprotocol/conformance@github:<owner>/conformance#<branch>

Examples:

npm install --no-save @modelcontextprotocol/conformance@github:modelcontextprotocol/conformance#main
npm install --no-save @modelcontextprotocol/conformance@github:myuser/conformance#sep-2350-check

Run Tests

Run client conformance tests with dotnet test filter:

dotnet test tests/ModelContextProtocol.AspNetCore.Tests/ModelContextProtocol.AspNetCore.Tests.csproj -f net10.0 --filter "FullyQualifiedName~ClientConformanceTests"

Run server conformance tests with dotnet test filter:

dotnet test tests/ModelContextProtocol.AspNetCore.Tests/ModelContextProtocol.AspNetCore.Tests.csproj -f net10.0 --filter "FullyQualifiedName~ServerConformanceTests"

Reporting

Always report:

1. Installed conformance source (npm ls @modelcontextprotocol/conformance --depth=0)
2. Scenario results (pass/fail/warnings)
3. Any new check IDs observed (for traceability)

Cleanup / Restore

Return repo to pinned dependency state:

npm ci
