Lint and fix an MCP (Model Context Protocol) server's source for what breaks the agent calling it — missing or vague tool descriptions, undocumented or untyped parameters, swallowed errors, stdout writes that corrupt a stdio transport — plus a separate security grade (tool poisoning, dynamic exec, SSRF, secrets). Use when the user asks to check, lint, audit, grade, review or fix their MCP server or its tools, asks whether their MCP server is "ready", "good" or safe to ship, wants it fuzzed or…
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
# mcp-doctor Scan an MCP server with the `mcp-doctor` CLI (PyPI package `mcp-server-lint`), explain what it found in terms of what goes wrong for the agent, and fix it with the user's go-ahead. The scan reads source only and never starts the server. The runtime checks in section 6 do start it, so they run only when the user asks or agrees. Target path: the path the user gave (`$ARGUMENTS` in Claude Code), else the current directory. If the current directory holds several servers, ask which one rather than scanning a whole monorepo. ## 1. Pick a runner Use the first that works, and keep using it for the rest of the session: 1. `mcp-doctor` (already installed; no network needed) 2. `uvx --from mcp-server-lint mcp-doctor` (downloads from PyPI on first use) 3. `pipx run --spec mcp-server-lint mcp-doctor` Below, `MCPD` means the runner you picked. …

How to install
mdr add vishalhabib99/mcp-doctor/mcp-doctor@sha256:55a1068e4908a511The line at the top of this page pins the label git:20261018.7c955e7, 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.
