Implementation Reference

• src/linkedin_mcp_server/adapters/driving/mcp_tools/session.py:17-29 (registration)

  MCP tool registration with @mcp.tool decorator. Registers 'close_browser' with description and defines the handler that wraps the use case, returning a dict with is_valid and message fields.

  @mcp.tool(
      name="close_browser",
      description="Close the browser instance and release resources. Credentials are preserved.",
  )
  async def close_browser(ctx: Context) -> dict[str, Any]:
      try:
          result = await manage_session_uc.close_browser()
          return {
              "is_valid": result.is_valid,
              "message": result.message,
          }
      except Exception as e:
          map_domain_error(e, "close_browser")

• src/linkedin_mcp_server/application/manage_session.py:15-18 (handler)

  Core business logic implementation. Closes the browser instance via the BrowserPort and returns a SessionStatus indicating the browser is closed.

  async def close_browser(self) -> SessionStatus:
      """Close the browser instance and release resources."""
      await self._browser.close()
      return SessionStatus(is_valid=False, message="Browser closed")

• src/linkedin_mcp_server/domain/models/responses.py:25-31 (schema)

  SessionStatus dataclass schema. Defines the structure returned by the close_browser use case with is_valid (bool), profile_path (optional str), and message (str) fields.

  @dataclass
  class SessionStatus:
      """Represents the status of a browser session."""
  
      is_valid: bool
      profile_path: str | None = None
      message: str = ""

• src/linkedin_mcp_server/adapters/driving/mcp_tools/session.py:21-27 (handler)

  MCP tool handler function. Receives Context, calls manage_session_uc.close_browser(), and transforms the SessionStatus result into a dict response with error handling.

  async def close_browser(ctx: Context) -> dict[str, Any]:
      try:
          result = await manage_session_uc.close_browser()
          return {
              "is_valid": result.is_valid,
              "message": result.message,
          }

• src/linkedin_mcp_server/adapters/driving/mcp_server.py:37-37 (registration)

  Registration call site. Invokes register_session_tools to register the close_browser tool with the MCP server instance.

  register_session_tools(mcp, container.manage_session)
