-Manager will get its own subcommand later with `request_spawn`, `kill`,
-`request_apply_commit` added to the TOOLS list.
+The manager (`hive-m1nd`) runs the same loop with a `ManagerServer` MCP
+flavor:
+- `mcp__hyperhive__send`, `recv` — agent surface.
+- `mcp__hyperhive__request_spawn(name)` — queue Spawn approval.
+- `mcp__hyperhive__kill(name)` — graceful stop of a sub-agent.
+- `mcp__hyperhive__request_apply_commit(agent, commit_ref)` — submit a
+  config change for any agent (`hm1nd` for self-modification).

+The shared per-turn plumbing lives in `hive_ag3nt::turn::{write_mcp_config,
+run_turn}` so both binaries can't drift apart.
