atlas f0844f6da3 agent permissions: one set, tool groups included, set at agent creation
mara on #5170: "dont split caps and perms. its all perms. / dont include
the now empty tool groups / nothing set -> default / also add perms to
agent creation screen".

- hive-sh4re: one `Permission` enum (messaging, meta, inbox, execution,
  web_tools, manage_root_agent) replaces `ToolGroup` and `Capability`;
  `lifecycle`/`forge` are gone. `Permission::default_for` is the default
  for an agent the swarm sets nothing for.
- The record is `{ "permissions": [...] }`. Missing key, unset field or
  no successful read yet = default; `[]` = none; a failed read after a
  good one keeps the last value.
- hive-agent reads its own key every 10s and builds each turn's --tools,
  --allowedTools and MCP config (rewritten before every turn) from it;
  the subagent daemon reads it on each start/continue. Agents get a
  read-only grant on their own key.
- hive-c0re restarts an agent only when its manage_root_agent changes.
  The import now merges meta/capabilities.json and meta/tool-groups.json
  into one list per agent and deletes both; the "import pending, don't
  read" decision is `ImportOutcome::read_allowed`, table-tested.
- swarm-controller: `GET /api/permissions` (names + default) and an
  optional `permissions` on `POST /api/agents`, stored before the job is
  queued. swarm-ui's create-agent form gets a permissions field.
- Deleted: HIVE_TOOL_GROUPS and its forward to the subagent daemon,
  tool_groups.rs, ruth's tool-group seed, the permissions rebuild job
  (PermPayload/WritePermFile/perm_change), the dashboard permissions tab
  and its stale-entries panel.

Part of #5170.

hive-agent-mcp

The built-in hyperhive MCP server every agent gets by default. Runs a long-lived streamable-http listener (the hive-mcp-http systemd unit) that claude reconnects to each turn via --mcp-config — this avoids the per-turn stdio re-registration race that a spawned-per-turn server would hit. HTTP is the sole transport; there is no stdio mode here.

When to use it

This is where the core hyperhive tool surface lives: send, recv, remind, get_loose_ends, set_status and get_agent_meta. Reach for this crate when you're adding or changing a built-in tool rather than an extraMcpServers add-on — those are separate stdio bridges (see hive-bash-mcp, hive-matrix-mcp) that dial the harness socket or their own daemon instead of living here.

Shape

  • mcp/ — the tool surface itself: one handler per tool, dispatch through client.rs back into the hyperhive broker (/run/hive/mcp.sock) or, for loose-ends v2 (todos/reminders), the in-agent socket the hive-agent harness serves.
  • client.rs — socket client to the hyperhive broker.
  • send_allow.rs — enforces the per-agent hyperhive.allowedRecipients allow-list on send.
  • paths.rs — socket + state path resolution shared with the harness's own paths.rs conventions.

Sibling of hive-agent (the serve loop that renders the --mcp-config blob pointing here). Standalone bin crate so the always-on MCP server doesn't need to link the whole turn-loop lib.
