Prepare a fix for a bug mcp-doctor finds in SOMEONE ELSE'S MCP server — a local clone of an open-source repo the user doesn't own — as a ready-to-review pull-request draft. It reproduces the bug with a failing test, applies one kind of fix, runs the repo's own tests, and writes the PR description in the repo's template, then stops for the user to review. It never pushes, opens a PR, or posts anything. Use when the user asks to fix, patch or contribute a fix upstream to another project's MCP…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# fix-upstream Turn one mcp-doctor finding in someone else's MCP server into a pull-request draft a maintainer is likely to merge. The bar is that the user would send it unchanged. **A wrong PR costs more than no PR**: it wastes a stranger's time and spends the user's reputation. When in doubt, stop and say why. Target: the path the user gave (`$ARGUMENTS` in Claude Code), else the current directory. It must be a git clone of a repo the user doesn't own. If it's the user's own server, use the `mcp-doctor` skill instead. Runner: as in the `mcp-doctor` skill (`mcp-doctor`, else `uvx --from mcp-server-lint mcp-doctor`, else `pipx run --spec mcp-server-lint mcp-doctor`), called below `MCPD`. This skill needs `--fix-only`; if `MCPD --help` doesn't list it, ask the user to upgrade `mcp-server-lint` and stop. ## Scope: one kind of fix per PR …

How to install
mdr add vishalhabib99/mcp-doctor/fix-upstream@sha256:8fcdd7fd06a4fc48The line at the top of this page pins the label git:20261017.231c22f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
