Implementation Reference

• tools/postman_tools.py:74-92 (handler)

  The GetAuthenticatedUserTool class is the handler for 'getAuthenticatedUser'. It extends ToolHandler and implements run_tool() which calls POSTMAN API GET /me and returns the result as JSON.

  class GetAuthenticatedUserTool(ToolHandler):
      """Get authenticated user information"""
      
      def __init__(self):
          super().__init__("getAuthenticatedUser")
      
      def get_tool_description(self) -> Tool:
          return Tool(
              name=self.name,
              description="Gets information about the authenticated user. Use this to get current user context (user.id, username, teamId, roles) for 'my ...' requests.",
              inputSchema={
                  "type": "object",
                  "properties": {},
              },
          )
      
      async def run_tool(self, args: dict) -> list[TextContent]:
          result = await postman_api_call("GET", "/me")
          return [TextContent(type="text", text=json.dumps(result, indent=2))]

• tools/postman_tools.py:80-88 (schema)

  The inputSchema for 'getAuthenticatedUser' is defined in get_tool_description(). It requires no parameters (empty properties object), as it simply returns info about the authenticated user.

  def get_tool_description(self) -> Tool:
      return Tool(
          name=self.name,
          description="Gets information about the authenticated user. Use this to get current user context (user.id, username, teamId, roles) for 'my ...' requests.",
          inputSchema={
              "type": "object",
              "properties": {},
          },
      )

• tools/postman_tools.py:1831-1835 (registration)

  The tool is registered in the register_all_tools() function by instantiating GetAuthenticatedUserTool() and including it in the returned list of handlers.

  def register_all_tools() -> list[ToolHandler]:
      """Register all Postman tool handlers"""
      return [
          # User Info
          GetAuthenticatedUserTool(),

• tools/postman_tools.py:21-67 (helper)

  The postman_api_call helper function is called by the handler to make the GET /me API request to Postman API.

  async def postman_api_call(
      method: str,
      endpoint: str,
      body: dict | None = None,
      params: dict | None = None,

  ) -> dict:
      """Make an API call to Postman API"""

          raise RuntimeError("POSTMAN_API_KEY environment variable is not set")
      
      url = f"{POSTMAN_BASE_URL}{endpoint}"
      
      # Prepare headers
      request_headers = {
          "X-Api-Key": POSTMAN_API_KEY,
          "Content-Type": "application/json",
      }
      if headers:
          request_headers.update(headers)

              if response.status_code == 204:
                  return {"success": True, "message": "Operation completed successfully"}
              
              return response.json() if response.content else {"success": True}

  The ToolHandler base class (ABC) that GetAuthenticatedUserTool extends. It requires implementing get_tool_description() and run_tool().
