Connect your GitHub coverage reports to Codex, Claude, and other MCP-compatible agents. Identify uncovered changes, write focused tests locally, and verify the result with GitHub checks.
After installing the GitHub App and uploading coverage, use 9to5 coverage directly in Codex’s in-app browser without configuring MCP, or configure remote MCP for access from Codex, Claude, and other compatible coding agents.

See project, patch, file, and line coverage on the pull request’s Files changed page. Covered and uncovered executable lines stay visible in split and unified diffs.
One signal · two audiences
Percentages tell you risk exists. 9to5 provides the coordinates to resolve it, with a workflow designed for agents and reviewers alike.
Target resolution
Query exact changed paths, contiguous uncovered ranges, nearby hit states, and the baseline behind every result.
Baseline intelligence
Compare project, file, and line states against the matching base branch run. Regressions surface without static-threshold noise.
Human review
Keep project and patch checks, pull request comments, and drill-down run pages in the GitHub workflow your team already trusts.
9to5 coverage — Patch coverage
Check completed in 18s
Read-only by design
MCP exposes authorized coverage metadata—never repository source. The coding agent reads code locally and uses 9to5 only to find and verify the right targets.
Closed-loop workflow
Every step has a clear owner. CI produces coverage, 9to5 resolves context, your agent works locally, and GitHub records the result.
