DiffCI is a remote MCP server that gives an AI agent 3 tools, among them diffci_interpret_report, diffci_validation_plan, diffci_verify_workflow_text. It answers at https://diffci.com/mcp/v1 over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 3 of 4 times since 23 September 2026; the last check, on 7 November 2026, succeeded.
Verification for AI coding agents: runs the tests and checks a change affects, with a receipt.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
diffci_interpret_report | Validate and summarize a DiffCI observation report, including selective or full mode, affected-test counts, fallbacks, non-interference evidence, and the conservative next action. Inputs: report |
diffci_validation_plan | Plan change-aware CI validation, affected-test selection, test impact analysis, or GitHub Actions workflow checks. Returns a safe local DiffCI command without accessing the checkout or executing it. Inputs: action, repo, platform |
diffci_verify_workflow_text | Perform a stateless preliminary safety check of GitHub Actions YAML: dedicated observer job, continue-on-error, dependency isolation, read-only permissions, and immutable DiffCI references. Inputs: workflow |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://diffci.com/mcp/v1. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.diffci. Endpoint host: diffci.com. ARD identifier: urn:air:io.github.diffci:mcp:diffci.
First indexed 22 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
