test(mcp): regression test for StdioTransport.send_notification
...
Follow-up on @Dilligaf371's PR #339 fix. Adds a regression test that
spawns a subprocess which consumes stdin without ever writing to
stdout, then issues `send_notification` from a worker thread. If the
override is missing, the thread blocks forever on `proc.stdout.readline()`
and the 2-second join timeout fires.

feat: fix external MCP server integration and add streaming tool-call support
...
Rebased and cleaned-up version of PR #113 by @mricharz, resolved against
current main (including Codex engine, Gemini thought_signature, and
agent manager fixes merged since the original PR).
MCP Transport & Client:
- StreamableHTTPTransport with session tracking, SSE parsing, timeouts
- MCPClient.initialize() sends proper MCP handshake (protocolVersion,
capabilities, clientInfo) + notifications/initialized
- Fix StdioTransport constructor: command=[command] + args
- MCPRequest.to_dict() with notification support (id=None)
External MCP Discovery:
- _discover_external_mcp supports both url (HTTP) and command (stdio)
- Per-server include_tools / exclude_tools filtering
- MCP clients persisted on JarvisSystem for runtime lifetime
Streaming Tool-Call Support (stream_full):
- StreamChunk dataclass in _stubs.py (content, tool_calls, finish_reason, usage)
- Default stream_full() on InferenceEngine ABC wraps stream() for backward compat
- _OpenAICompatibleEngine.stream_full() with SSE parsing
- CloudEngine: _stream_full_openai (OpenAI/OpenRouter/MiniMax/Codex routing)
_stream_full_anthropic (event-based → OpenAI delta format)
- InstrumentedEngine, MultiEngine: stream_full delegation
- GuardrailsEngine: stream_full with post-hoc security scanning (FIXED:
original PR bypassed output scanning — now accumulates and scans like stream())
Other improvements:
- _prepare_anthropic_messages() extracted to eliminate duplication
- Default tool_choice=auto when tools are provided (OpenAI compat engines)
- MCP tool injection into managed agent streaming path
- Documentation: docs/user-guide/mcp-external-servers.md
Tests: ~59 new tests across 8 test files, all passing.
Closes PR #113
