Install, deploy, register, or set up the subagent-mcp addon (MCP server + orchestration-mode hooks) standards-compliant across every supported vendor (currently Claude Code CLI and Codex CLI; expandable). Ships ALL parts : MCP stdio server, per-turn hooks, and directive assets : to a PERMANENT, repo-decoupled location and wires each vendor with its official mechanism. Use when asked to "install subagent-mcp", "install the mcp", "install this", "deploy subagent-mcp", "set up subagent-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
# subagent-mcp Installer Deploy the **subagent-mcp** addon : the MCP stdio server **plus** the per-turn `orchestration-mode` hooks and their directive assets : to a **permanent, repo-decoupled location**, then register it with each supported vendor using that vendor's **official, standards-compliant** mechanism. **Input** = the host machine + which vendors are present (Claude Code CLI, Codex CLI). **Output** = a working, verified install that does NOT reference the dev repo, a worktree, or any temp path. This skill is the authoritative install SOP. It supersedes the absolute-path-to- repo examples in `docs/install/*` (those point at the build tree; this ships a decoupled copy). When they disagree, **this skill wins**. ## Non-negotiable rules 1. **Permanent location only.** Install to the global npm package dir (`npm root -g` → `<root>/@heretyc/subagent-mcp`) or another stable, user-owned dir. **NEVER** install from or point config at: a git **worktree**, `%TEMP%`, `/tmp`, `/TMP`, `$TMPDIR`, `os.tmpdir()`, a `Downloads` folder, or the live dev checkout. See `references/locations.md` for the full forbidden list and …

How to install
mdr add heretyc/subagent-mcp/subagent-mcp-installer@sha256:5034d5866499455aThe line at the top of this page pins the label v1.0.0, 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.
