- Replace Args: docstring blocks with Annotated[str, Field(description=...)]
so parameter descriptions appear in inputSchema.properties.*.description
- mcp.server.fastmcp does not parse Args: blocks from docstrings;
only Annotated with pydantic Field injects descriptions into the
structured JSON Schema visible to AI clients via tools/list
- Remove redundant Args: blocks from docstrings (info moved to Field)
- Restore full 4-step websocat workflow in get_node_console_info docstring
with connection, command sending, response receiving, and timeout
- SSE endpoint supports both Authorization: Bearer header and ?token= query param
- Claude Code can use headers (no URL exposure)
- Claude Desktop (EventSource) can use ?token= URL param
- Use FastMCP (Anthropic MCP SDK) for tool registration and SSE transport
- Mount SSE app under /v3/mcp/transport with JWT token authentication
- Token passed via ?token=<jwt> query parameter on SSE connection
- Token validated against GNS3 auth_service and stored in contextvars
- Tool handlers create Gns3Connector with JWT token to call GNS3 REST API
- 7 project tools: list_projects, get_project, create_project, delete_project,
open_project, close_project, get_project_stats
- Unauthenticated SSE connections return 401
- Add MCPTool/MCPToolRegistry system for centralized tool registration
- Add 7 project-related MCP tools: list_projects, get_project, create_project,
delete_project, open_project, close_project, get_project_stats
- Tools use Gns3Connector (custom_gns3fy) to call GNS3 REST API via HTTP loopback,
keeping the MCP layer decoupled from controller internals
- Handlers run in thread pool via asyncio.to_thread() to avoid blocking
the event loop on synchronous requests calls
- Unified POST /v3/mcp/execute endpoint with JWT authentication
