Steps

  1. Start aish with EMPTY mcp.servers = {} (or no mcp block at all).
  2. Run :mcp list — should report (no MCP sessions).
  3. Run :mcp connect http://boltzmann.fritz.box:8080/mcp boltzmann. If you can't supply BOLTZMANN_MCP_TOKEN via env, this test won't work unless you tweak the URL to a no-auth lmcp (broglie if reachable, or higgs).
    • Actually, with auth_env not set in the runtime form, you'd need to construct a connect path differently — or pass through a config-declared session.
    • Simpler steps: pre-configure two servers in mcp.servers (say boltzmann and hertz), boot, then test disconnect/reconnect on hertz.
  4. Run :mcp list — should now show the connected session.
  5. Run :mcp disconnect <alias>.
  6. Run :mcp list — should be empty again (or just the surviving one).
  7. Try :mcp disconnect <same-alias> again — should report not connected: <alias>.

Expected

  • Each meta runs cleanly, status lines accurate.
  • Disconnect doesn't crash, and subsequent tool-call attempts targeting the disconnected alias get the synthesized [aish] no MCP server connected for alias '...' tool turn (verified by triggering a prompt that asks for the disconnected server's tool).

What this exercises

  • :mcp connect <url> [alias] meta — URL parsing, alias derivation, initialize, tools/list cache.
  • :mcp disconnect <alias> meta — drop from mcp_sessions table.
  • Reconnect-after-disconnect path.
  • dispatch_tool_call graceful degradation when alias is no longer connected.

Known limitation

Runtime :mcp connect has no inline way to specify Bearer auth — auth is config-only. Filing as a separate feature request if needed.

## Steps 1. Start aish with EMPTY `mcp.servers = {}` (or no `mcp` block at all). 2. Run `:mcp list` — should report `(no MCP sessions)`. 3. Run `:mcp connect http://boltzmann.fritz.box:8080/mcp boltzmann`. If you can't supply BOLTZMANN_MCP_TOKEN via env, this test won't work unless you tweak the URL to a no-auth lmcp (broglie if reachable, or higgs). - Actually, with `auth_env` not set in the runtime form, you'd need to construct a connect path differently — or pass through a config-declared session. - **Simpler steps**: pre-configure two servers in `mcp.servers` (say boltzmann and hertz), boot, then test disconnect/reconnect on hertz. 4.

PASS with documented limitation (executed 2026-05-12 at commit 3fa6279, against live boltzmann + hertz lmcp).

Three config-declared sessions on startup → both connected. Then:

  • :mcp list shows both ✓
  • :mcp disconnect hertz[aish] disconnected hertz
  • :mcp list shows only boltzmann ✓
  • :mcp disconnect hertz (already gone) → [aish] not connected: hertz
  • :mcp connect http://hertz.fritz.box:8080/mcp hertz[aish] mcp hertz: HTTP 401: {"error":"unauthorized"} (transport_error)expected per the test case's "Known limitation" section. Runtime :mcp connect has no inline auth syntax; auth is config-only.

Dispatcher graceful-degradation when targeting a disconnected alias not exercised here (would need to trigger a tool call after disconnect, which requires real LLM cooperation). Tracked via TC #30/#26 indirectly.

Closing.
